Which sentence uses comparison correctly? a. which tastes gooder to you, a hearty soup or a fresh salad? b. which tastes best to you, a hearty soup or a fresh salad? c. which tastes more better to you, a hearty soup or a fresh salad? d. which tastes better to you, a hearty soup or a fresh salad?

D is the only one that follows conventional grammar rules.

The rest are wrong because...

A- gooder is not a word

B- you are only comparing 2 things so you would say best, you would say better. The rule is 'good, better, best.' Best is only used to compare multiple things

C- You already said better so you don't need another adjective, more, to support that

Ithink your answer is b
