The correct answer is: Only assumption I is implicit.
The statement “Please consult us before making any decision on investment” implies that the speaker believes that the listener may make a wrong decision if they do not consult them. This is because the speaker is asking the listener to consult them before making a decision, which suggests that they believe that the listener may not be able to make a good decision on their own. However, the statement does not imply that it is important to take a right decision. It is possible that the speaker is simply trying to be helpful and does not have any particular opinion on whether or not it is important to make a right decision.
Here is a brief explanation of each option:
- Option A: Only assumption I is implicit. This is the correct answer. The statement implies that the listener may make a wrong decision if they do not consult the speaker. This is because the speaker is asking the listener to consult them before making a decision, which suggests that they believe that the listener may not be able to make a good decision on their own.
- Option B: Only assumption II is implicit. This is not the correct answer. The statement does not imply that it is important to take a right decision. It is possible that the speaker is simply trying to be helpful and does not have any particular opinion on whether or not it is important to make a right decision.
- Option C: Either I or II is implicit. This is not the correct answer. The statement only implies assumption I. It does not imply assumption II.
- Option D: Neither I nor II is implicit. This is not the correct answer. The statement does imply assumption I. It does not imply assumption II, but it does not explicitly state that assumption II is not true.
- Option E: Both I and II are implicit. This is not the correct answer. The statement only implies assumption I. It does not imply assumption II.
