Detailed Solution

Concept- We'll be able to comprehend the composite numbers. The prime factorization of a composite number will then be performed, and the numbers that are excluded from the prime factorization of composite numbers will be understood.
A positive integer called a composite number has at least one divisor besides itself and the number 1.
As an illustration, the integer 6 is a composite number since it contains two divisors other than itself and the number 1, 2, and 3.
Consider the composite number 21.
Using the 21-prime factorization, we obtain

Therefore, 21 can be written as the result of the numbers 3 and 7.
Therefore, 1 and 21 are the only elements that are left out of the prime factorization of 21. because although they are not prime numbers, 1 and 21 are also factors of 21.
In a similar vein, the prime factors of 12 are 2, 2, and 3 (composite number).
Therefore, the two components that are excluded from the prime factorization of a composite number are 1 and the number itself.
Hence, option 3 is correct.
