Correct Answer: (a) received in rupees against overseas currencies and vice versa without going through the official channels
Solution:Overseas transactions such as purchase-selling and of foreign currency should be done through authorized transfer dealers but transfer of black money generally made through using informal networks. Hawala is an informal method of transferring money without any physical money actually moving. Hawala provides anonymity in its transactions, as official records are not kept and the source of money that is transferred cannot be traced. Lets understand by an example, suppose a person (A) needs to send $200 to his wife (B), who lives in another country. He will approach a Hawala dealer H₁ (in his country) and give him the amount of money he wants wife to receive, including the details of the transaction. H, contacts a hawala dealer H, (in the recipient's country) and asks him to give $ 200 (in the value of domestic currency) to wife of (A). H₂ transfer the money from his own account, minus commission. And they (H, & H₂) settle this transaction in future. In India, under Prevention of Money Laundering Act, Hawala operations are illegal.
