To solve this question, we need to understand the concepts of prime numbers and composite numbers.
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. Examples of prime numbers include 2, 3, 5, 7, 11, 13, etc.
On the other hand, a composite number is a natural number greater than 1 that is not prime, meaning it has at least one divisor other than 1 and itself. Examples of composite numbers include 4, 6, 8, 9, 10, 12, etc.

Let's analyze the given statement step by step:

1. "The successor of a prime number": The successor of a number is the number that comes immediately after it. For example, the successor of 2 is 3, the successor of 5 is 6, etc.

2. "is predecessor of a composite number": The predecessor of a number is the number that comes immediately before it. For example, the predecessor of 3 is 2, the predecessor of 6 is 5, etc.

Now, let's consider the options given:

a) 11: The successor of 11 is 12, but 12 is not a composite number. It is divisible by 2, making it a composite number. Therefore, option 'a' is incorrect.

b) 17: The successor of 17 is 18, and the predecessor of 18 is 17. Here, 18 is a composite number as it is divisible by 2 and 3. Therefore, option 'b' is incorrect.

c) 23: The successor of 23 is 24, and the predecessor of 24 is 23. Here, 24 is a composite number as it is divisible by 2, 3, 4, 6, 8, and 12. Therefore, option 'c' is correct.

d) 29: The successor of 29 is 30, but 30 is not a composite number. It is divisible by 2, 3, 5, and 10, making it a composite number. Therefore, option 'd' is incorrect.

e) None of these: Since option 'c' (23) is the correct answer, option 'e' is incorrect.

Therefore, the correct answer to the question is option 'c' (23).

Correct ans is non of these. 12 is composite no. Why should you say it is not a composite no.
