Chocolate or Vanilla?

Which one of the following, if true, most strengthens the argument?

A recent taste test reveals that most people like low-fat chocolate ice cream as much as its full-fat counterpart. Previous tests with vanilla ice cream found that people tended to dislike low-fat versions, complaining of a harsher taste. Chemists point out that chocolate is a very complex flavor, requiring around 500 distinct chemical compounds to produce it. Hence, this complexity probably masks any difference in taste due to the lack of fat.

Answer: Vanilla is known to be a significantly less complex flavor than chocolate.
