Option 1 states that both the assertion and reason are true, and the reason is a correct explanation for the assertion. Option 2 also considers both the assertion and reason as true but does not consider the reason as an explanation for the assertion. Option 3 suggests that the assertion is true, contradicting the reason stating it is false. Lastly, Option 4 suggests the assertion is false while accepting the reason as true.

The correct answer marked here is option 3 which implies that "Information technology is fast becoming a very important field of activity in India" is correct, but "Software is one of the major exports of the country and India has a very strong base in hardware" is incorrect. The second point is false because although software is a major export, India doesn`t necessarily have a strong base in hardware to the same extent. Hence, only the assertion stands true in this context.
