Statement : The Central Bureau of Investigation receives the complaint of an officer taking bribe to do the duty he is supposed to. Courses of Action : I. CBI should try to catch the officer red-handed and then take a strict action against him. II. CBI should wait for some more complaints about the officer to be sure about the matter.

Only I follows
Only II follows
Either I or II follows
Neither I nor II follows E. Both I and II follow

The correct answer is: C. Either I or II follows

The CBI should try to catch the officer red-handed and then take a strict action against him. This is because if the officer is caught red-handed, it will be easier to prove his guilt and take action against him. Additionally, catching the officer red-handed will send a strong message to other officers that corruption will not be tolerated.

However, it is also possible that the CBI may not be able to catch the officer red-handed. In this case, the CBI may need to wait for some more complaints about the officer to be sure about the matter. Once the CBI has gathered enough evidence, it can then take action against the officer.

Therefore, either course of action I or II could follow.
