Explanation:

"Blabby", "gushing", and "wordy" are adjectives that convey the idea that one is overly talkative and expresses their ideas prolixly, that is, by using more words than it would be actually necessary. In other words, the adjectives in letters b, c, and d are used in order to criticize someone for the way they talk.

"Conversational" is an adjective used as a compliment: a conversational person, besides being fond of talking, has the ability to talk, that is, that person is skilled in conversation.
