Hi Dana,
Thanks for the question. Because you didn't ask about (A), I'll assume you understand how (A) weakens the argument.
In answer choice (B), there are multiple issues. The first is that the answer is extremely vague--"can be influenced" doesn't mean a whole lot, and when faced with this answer, the author could reply, "Yes, they can be influenced, but in this instance they weren't." Second, this answer can actually strengthen the argument by eliminating an alternate cause--the universality of preference for sweets in humans (if humans all share the same sweets preferences, that could explain why all children liked the sugary cereals, thus strengthening the idea that television advertising wasn't the cause).
Based on what you said in your original question, it looks like you took the "can be influenced" portion of (B) to mean that since sweet preferences aren't universal, TV must be the cause, but that interpretation goes too far.
Please let me know if that makes sense. Thanks!
