Correct option is C
The given statement does not confirm that some dogs are brown, only that some mammals are brown. There is no direct logical connection proving that dogs specifically belong to this subset.
· (a) Yes – Incorrect because it is not necessarily true.
· (b) No – Incorrect because it is possible, just not guaranteed.
· (d) It depends on more information – This is a weaker form of option (c).
Thus, the best choice is (c) Maybe.
