I would probably say plump.
Essentially, in this question, you're looking for the word that would be the least insulting. More broadly, when asked about positive connotation, you're looking for a word that is not viewed negatively.
Words like fat and cheap have negative connotations, especially when applied to people. Words like plump and frugal are much more positive.
The answer It’s either A or B the rest DONT add up
Watch television! It's way more entertaining and will not cause stomachaches, tooth decay and cavities lol
