The correct answer is: C. Either I or II is implicit.
The statement “There has been a remarkable increase in the air traffic in India during the past few years” does not provide enough information to determine whether assumption I or assumption II is implicit. It is possible that both assumptions are implicit, but it is also possible that neither assumption is implicit.
For example, it is possible that the increase in air traffic is due to the fact that more people are able to afford air travel now. This would support assumption II. However, it is also possible that the increase in air traffic is due to the fact that travelling by air has become a status symbol now. This would support assumption I.
Without more information, it is impossible to say for sure whether assumption I or assumption II is implicit. Therefore, the correct answer is C. Either I or II is implicit.
Here is a brief explanation of each option:
- Option A: Only assumption I is implicit. This option is incorrect because the statement does not provide enough information to determine whether assumption I is implicit.
- Option B: Only assumption II is implicit. This option is incorrect because the statement does not provide enough information to determine whether assumption II is implicit.
- Option C: Either I or II is implicit. This option is correct because the statement does not provide enough information to determine whether assumption I or assumption II is implicit.
- Option D: Neither I nor II is implicit. This option is incorrect because the statement does provide enough information to determine that assumption I or assumption II is implicit.
- Option E: Both I and II are implicit. This option is incorrect because the statement does not provide enough information to determine whether assumption I and assumption II are both implicit.
