Final answer:
The natural numbers that divide n are 1, 3, 11, and 33 because they are divisors of 33, which is a factor of n. This is explained by the fundamental theorem of arithmetic.
Step-by-step explanation:
If 33 divides n, the other natural numbers that divide n are 1, 3, 11, and 33. These numbers are all divisors of 33 and, by definition, if a number divides 33, it will also divide any multiple of 33, which includes n when 33 divides n.
Why do these other natural numbers divide n? The correct answer is A. Because they also divide 33, which is a factor of n. This is due to the fundamental theorem of arithmetic, which states that every integer greater than 1 is either a prime number or can be factored into a unique combination of prime numbers. Since 33 can be expressed as 3 x 11, both 3 and 11 are prime factors of 33 and thus are also factors of n.
