Q:

Banks should always check financial status before lending money to a client.

Assumptions : 

I. Checking before lending would give a true picture of the client's financial status.

II. Clients some times may not present the correct picture of their ability to repay loan amount to the bank.

A) If only assumption I is Implicit B) If only assumption II is Implicit
C) If either I or II is Implicit D) If both I and II are Implicit
 
Answer & Explanation Answer: A) If only assumption I is Implicit

Explanation:

I is implicit in the norm prescribed in the sentence. This is why checking is being advised. Again, what would the banks check? Obviously  what the clients reveal. Banks would assume the revelation to be true.Hence II is not implicit. However, II is vague. If cross - checking is what the speaker has in mind, II would become implicit.
