A composite number is a positive integer that has at least one positive divisor other than one and itself, which means it can be divided evenly by at least one other number.
From the choices given:
- 69: Composite (divisible by 1, 3, 23, and 69)
- 89: Prime (only divisible by 1 and 89)
- 29: Prime (only divisible by 1 and 29)
- 59: Prime (only divisible by 1 and 59)
Thus, the composite number is 69.
