The correct answer to the question is option 2: Indonesia.

India signed an agreement with Indonesia on 27th July, 2012, to avoid double taxation and prevent fiscal evasion with respect to taxes on income. This agreement is commonly known as the Double Taxation Avoidance Agreement (DTAA).

A DTAA is a bilateral agreement signed between two countries to define the tax treatment of income or capital in both countries to avoid double taxation. Double taxation occurs when the same income is taxed in both the country of residence and the country of source.

India has signed such agreements with several countries, including Indonesia. The purpose of these agreements is to promote trade and investment between the countries by providing relief from double taxation and ensuring fair tax treatment.

Therefore, the correct option is 2: Indonesia.
