The correct answer is C. like.
The verb “like” is used to express a feeling of enjoyment or pleasure towards something. In this case, the sentence is about most children’s feelings towards ice cream. Since most children enjoy ice cream, the correct verb to use is “like.”
The other options are incorrect because they do not express a feeling of enjoyment or pleasure. Option A, “likes,” is the simple present tense form of the verb “like.” However, the sentence is about most children’s general feelings towards ice cream, not about a specific instance of a child liking ice cream. Option B, “were liking,” is the past tense form of the verb “like.” However, the sentence is about most children’s current feelings towards ice cream, not about a past instance of children liking ice cream. Option D, “are like,” is the present tense form of the verb “to be like.” However, the verb “to be like” is used to compare two things, not to express a feeling of enjoyment or pleasure.
