Concept: The binary operation defines a custom rule for combining two integers. Evaluate the bracket first, then apply the operation again.Explanation:The rule is p∗q=pq+p−q. Start with the bracket: 3∗4. Here p=3 and q=4. So 3∗4=(3)(4)+3−4=12+3−4=11. Now evaluate 2∗(3∗4)=2∗11. Here p=2 and q=11. So 2∗11=(2)(11)+2−11=22+2−11=13.Answer:13 Option B is correct.
