Incorrect.

To solve this Assumption question, first break down the argument. Sentences 1 and 2 are factual, so they are the premises, while sentence 3 includes the word concluded so it's the conclusion.

Now ask yourself: the author believes that the salesman likes playing electric guitar better than playing classical guitar becuase he gets higher commissions playing electric guitar. What must the author assume for this argument to stand?

The number of guitars sold is irrelevant, as it does not explain why the author concluded the salesman prefers playing the electric guitar.

B. The salesman's enjoyment as a guitarist is based only on the amount of money he earns by playing.

To reach the given conclusion, the author must assume that the salesman's earnings are the only thing that makes him enjoy playing guitars.

IMHO the only thing that can link "The music store gives the salesman a 5% commission for every guitar that he sells" and "It can be concluded that the salesman enjoys playing on an electric guitar more than he does on a classical guitar" is the fact that the salesman +plays -> +sells -> +earns -> +enjoys playing on an electric guitar

The salesman's enjoyment as a guitarist is based only on the amount of money he earns by playing -> B

The salesman's enjoyment as a guitarist is based only on the amount of money he earns by playing -> B
