Yes, 43 is a two-digit odd number because it has two digits and is not divisible by 2. It is a prime number because it can only be divided by 1 and itself. A composite number is a positive integer greater than 1 that has at least one positive divisor other than 1 and itself, so 43 is not a composite number.
