Explanation

In a federal constitution, there are usually two levels of government: the national/federal government and the state/provincial government. Legislative powers refer to the ability to make laws. In a federal constitution, there are some legislative powers that are shared by both levels of government. This means that both the national/federal government and the state/provincial government have the power to make laws on that particular issue.

The question is asking what these shared legislative powers are called. The options given are: Exclusive, Concurrent, Extra-ordinary, and Residual. The correct answer is Option B: Concurrent. This means that in a federal constitution, legislative powers that are shared by both levels of government are referred to as concurrent powers.

Exclusive powers refer to legislative powers that are only given to one level of government, either the national/federal or the state/provincial government. Extra-ordinary powers are usually given to the national/federal government in times of emergency or crisis. Residual powers refer to legislative powers that are not specifically assigned to either level of government and thus are left to the discretion of the national/federal government.

It is important to understand the different types of legislative powers in a federal constitution to understand how laws are made and who has the authority to make them.
