Solution

The correct option is B 40
Clearly, according to the given conditions, there are 15 boys to the left of A, as well as to the right of C. Also, B lies between A and C such that there are 3 boys between A and B and 4 boys between B and C. So, number of boys in the row.
=(15+1+3+1+4+1+15)=40.
