The correct answer is option 1, which states that statements 1, 2, and 3 are correct. Now let`s dissect each option to understand why.

Option 1 states that statements 1, 2, and 3 are correct. Statement 1 is indeed correct. The Financial Action Task Force (FATF) is an intergovernmental body that develops policies to combat money laundering and terrorist financing. It was established in 1989 and is considered the global standard setter for these issues.

Statement 2 is also correct. India is a full-fledged member of the FATF. It became a member in 2010 and has actively participated in its initiatives and discussions.

Statement 3 is correct as well. FATF membership provides India with the opportunity to access information on suspicious accounts in nations such as Switzerland and the UK. This access to cross-border information is crucial for effectively combating money laundering and terrorist financing.

Therefore, all three statements are correct, making option 1 the correct answer.
