India offered to build a Buddha Temple in China, which is reflected in option 1. Here is a breakdown of all options:

Option 1: China - This is the correct answer. The move is indicative of the cultural connection between the two countries and is likely aimed at fostering stronger ties.

Option 2: Myanmar - This is incorrect. India has robust cultural links with Myanmar, but no recent offer of building a Buddha Temple is recorded.

Option 3: Thailand - This is incorrect too. Thailand is heavily influenced by Buddhism, and it has many Buddha Temples already. The Indian Government has not proposed to build a Buddha Temple there recently.

Option 4: Vietnam - This is not the correct answer either. Though Vietnam possesses a significant Buddhist population, there has been no recent offer from India to build a Buddha Temple.

This answer is generally correct. The key to understand here is the subject of the sentence, `India`, which is making an offer to China, not any of the other listed countries. It underscores the cultural diplomacy between India and China.
