This question requires knowledge of recent international events and economic relationships. The first statement is false as the 15th ASEAN- India Summit was not held virtually in March 2022. The second statement is also incorrect. The EU is certainly a significant trading partner for India, but it is not the largest regional trading partner. ASEAN is India`s largest regional trading partner. Hence, neither of the statements is correct, so the correct answer is option 4 - "Neither 1 nor 2". This option refers to both statements being incorrect, which is the case in this scenario.
