Which of the assumptions given in the options is implicit in the statements?

Statements:

(1) All Explosives are Sound.

(2) Some Bombs are Exclusively Sound.

(3) Some light are Bombs but not Sound.

Let's analyze all Assumptions:
A. Some Bombs are Explosives: (Not Implicit)
This is not implicit from the given statements. There's no direct statement that connects bombs to explosives.
B. All Sounds are Explosives:  (Not Implicit)​
This is not implicit. The statement "All Explosives are Sound" doesn't imply that all sounds must be explosives.
C. Some Explosives are Lights: (Not Implicit)​
This is not implied. The given statements do not suggest that any explosives are lights.
D. Some Sounds are only Bombs: (Implicit)​
This is implicit. Since  ("Some Bombs are Exclusively Sound") means that some sounds are only bombs and nothing else.
Thus, the correct option is (d) Some Sounds are only Bombs.
