If 11 and 3 are factors of a number, then 11×3=33 is also a factor of that number.
The correct option is A: True
11 and 3 have no common factors other than 1, i.e., 11 and 3 are co-prime.
If two factors of a number are co-prime, then their product is also a factor of that number.
11×3=33 is also a factor of that number.
