(A) of
(B) in
(C) to
(D) from
The best option to fill the blank is:
(C) to
Here’s why:
- Of: “Of” wouldn’t be appropriate here. It can indicate possession or origin, which doesn’t make sense in this context.
- In: “In” might suggest “within” ultimate happiness, which isn’t quite what the sentence means.
- To: “To” indicates the direction or goal. Ambition doesn’t necessarily lead directly to ultimate happiness (although it can contribute). This is the most fitting choice.
- From: “From” suggests a source, which doesn’t fit the meaning either.
Therefore, “ambition does not always conduce to ultimate happiness” expresses the idea that ambition doesn’t guarantee ultimate happiness.
