Explanation

The correct answer is Option B: Bank drafts drawn by commercial banks on their foreign branches.

A bank draft is a type of payment instrument that is issued by a bank. It is like a check, but it is guaranteed by the bank. When a bank draft is drawn on a foreign branch of a commercial bank, it means that the payment is made using a draft issued by a bank in one country and payable in another country. This is a common and secure method of payment in international trade.

Option A, Central Bank cheques, refers to checks issued by the central bank of a country. While central banks play a role in regulating and overseeing the banking system, they are not typically involved in individual foreign trade transactions.

Option C, Irrevocable and confirmed letters of credits, is another method of payment used in foreign trade. Letters of credit are issued by banks and guarantee payment to the seller if certain conditions are met. However, this method is not as commonly used as bank drafts.

Option D, Letters of credit authenticated by the embassies of the respective countries, is not a common method of payment in foreign trade. The authentication of letters of credit by embassies is not a standard practice.

To summarize, most foreign trade transactions are paid through the use of bank drafts drawn by commercial banks on their foreign branches. This is a secure and widely used method of payment in international trade.
