Option 1 states that both statements are individually true and statement II is the correct explanation of statement I.

Statement I is true as India has shown support for the development and utilization of the Chabahar Port in Iran. The port holds strategic significance for India as it provides a trade route that bypasses Pakistan and allows India to access Afghanistan and Central Asian markets.

Statement II is also true as India has not subscribed to Western sanctions on energy trade with Iran. Despite pressure from the West, India has maintained its energy ties with Iran and has continued to import oil and gas from the country.

However, option 1 claims that statement II is the correct explanation of statement I. While statement II provides additional information related to India`s stance on Western sanctions, it does not directly explain why India supports the Chabahar Port. Therefore, option 1 is not the correct answer.

Option 2, on the other hand, correctly identifies that both statements are individually true but statement II is not the correct explanation of statement I. This is because statement II does not provide a direct explanation for India`s support of the Chabahar Port. Therefore, option 2 is the correct answer to the question.
