Solution

The correct option is C 14
In the first choice, the teacher can select a boy among 10 boys in 10 ways (who ever may be of the 10 boys).
In the second choice, the teacher can select a girl among 4 girls in 4 ways (who ever may be of the 4 girls).
Hence, the teacher can select the class leader who is a boy or a girl in 14 different ways (10 boys + 4 girls).
