There are 20 players in Maxvu's sports team, numbering from 1 to 20. What is Maxvu's number? Of the choices below, only one is correct.

A. an odd number
B. an even number
C. a prime number
D. a composite number


It's easily seen that one of A and B must be correct, as a number is either odd or even. This means that neither C nor D is correct. If a number is neither prime nor composite, it can only be 1, so choice A is correct.
