When did India test a nuclear device for the first time?

1974

The correct answer is Option 1 - 1974

In 1974 India tested the nuclear device for the first time.

The first component was streng thening its military capabilities because India has been involved in conflicts with its neighbours — Pakistan in 1947–48, 1965, 1971 and 1999; and China in 1962. Since it is surrounded by nuclear-armed countries in the South Asian region, India’s decision to conduct nuclear tests in 1998 was justified by the Indian government in terms of safeguarding national security. India first tested a nuclear device in 1974.
