Ajmal doesn’t want to argue with you, “yet” he doesn’t want to give in. The correct answer is represented by option C.
In this sentence, we are presented with two opposing points. (1) Ajmal does not want to argue with you, and (2) he does not want to give in. By not giving in, Ajmal would continue to argue with you. Because the two clauses of the sentence represent different views, the word “yet” is used.
The term “so” would be used in a cause and effect situation. This transforms the sentence into the conversion of: Ajmal doesn’t want to argue with you, so he gives in.
Using the word “for” describes a situation where one part of the sentence is being explained by another. This converts the sentence into: Ajmal gives in, for he does not want to argue with you.
The word “and” is used as a way of addition to what’s initially being said, which in this case is that Ajmal does not want to argue. While it would make sense grammatically to insert the term “and” into this sentence, it isn’t relevant because the two clauses contradict each other.
Therefore, option C is correct.
