Correct Answer: D) Cochlea

Explanation

The ear is an important organ that helps us to hear sounds. The ear is divided into three parts: the outer ear, the middle ear, and the inner ear. The part of the ear that contains receptors that convert the fluid motion into action potential is called the cochlea. The cochlea is located in the inner ear and is shaped like a snail shell. It is filled with fluid and lined with tiny hair cells that are sensitive to vibrations. When sound waves enter the ear, they cause the fluid in the cochlea to move, which in turn causes the hair cells to bend. This bending of the hair cells generates electrical signals which are sent to the brain via the auditory nerve, where they are interpreted as sound. The other options listed in the question are also important parts of the ear, but they do not contain receptors that convert fluid motion into action potential. The auditory nerve is responsible for transmitting the electrical signals generated by the hair cells to the brain. The ossicles are three small bones in the middle ear that amplify sound vibrations. The semicircular canals are responsible for our sense of balance and help us to maintain our equilibrium. The oval window is a membrane between the middle ear and the inner ear that transmits sound vibrations from the ossicles to the cochlea. Therefore, the correct answer to the question is option D: Cochlea.

Correct Answer: B) Comparative cost advantage

Explanation

Option A: Balance of payment. Balance of payment refers to the record of all transactions between a country and the rest of the world over a specific period. While balance of payment is related to international trade, it does not describe the reason for international trade.

Option B: Comparative cost advantage (Correct). Comparative cost advantage is the ability of a country to produce a good or service at a lower opportunity cost compared to other countries. This means that a country can produce a particular good or service more efficiently and at a lower cost than other countries. This is one of the main reasons for international trade. Countries engage in international trade to take advantage of their comparative cost advantage and exchange goods and services with other countries to benefit from specialization and increase overall economic welfare.

Option C: Absolute cost advantage. Absolute cost advantage refers to a situation where a country can produce a good or service at a lower cost compared to other countries. While absolute cost advantage can be a reason for international trade, it is not the best description of the reason for international trade.

Option D: Balance of trade. Balance of trade refers to the difference between the value of a country's exports and the value of its imports. While balance of trade is related to international trade, it does not describe the reason for international trade.

Therefore, the correct answer is Option B: Comparative cost advantage, as it best describes the reason for international trade. Countries engage in international trade to take advantage of their comparative cost advantage and increase overall economic welfare.
