Explanation:

Here’s the thing, let's break it down:

- The sentence is: "The French perfume has a wonderful ________."

- Option 1: sent – This is the past tense of "send." Has nothing to do with smells.

- Option 2: send – This is a verb, like "I send a letter." Doesn't fit the sentence at all.

- Option 3: scent – This is the word for a smell or fragrance. Perfect fit for describing perfume.

- Option 4: cent – This is a unit of money, like a penny. Not related here.

What this really means is, the only option that makes any sense in this blank is "scent."
