Step 1: Understanding the Concept.
The Look East Policy is India's strategy, launched in the early 1990s, to build stronger economic and strategic ties with Southeast and East Asia.
Step 2: Check statement 1.
One clear aim of the policy is for India to be seen as a significant player in East Asian affairs, so statement 1 is true.
Step 3: Check statement 2.
The policy is not framed as filling a gap left by the end of the Cold War; it is instead a response to India's own post-1991 economic liberalisation and the need for new markets and partners. Statement 2 is not one of its stated goals, so it is false.
Step 4: Check statement 3.
Reviving old cultural, civilisational, and trade links with Southeast and East Asian neighbours is one of the core goals of the policy, so statement 3 is true.
Step 5: Final Answer.
Statements 1 and 3 are correct, so the answer is option B, 1 and 3 only.
