English 2023 Q53: Fill each gap with the most appropriate option from the list provided. We had to ….. the group headed by Taiwo.

The phrasal verb sell out can mean to betray. “We had to sell out the group headed by Taiwo” means they gave the group up for gain.

sell off means to sell cheaply to get rid of stock, and sell up means to sell a home or business. Neither fits a group of people. selled is not a word, because the past tense is “sold”.
