Correct answer and explanation
Correct answer: 63
Explanation: ✅ Correct Answer: B. 63 📚 Explanation: In the given series 53, 59, 63, 67, 71, all the numbers except 63 are prime numbers. A prime number is a number that is only divisible by 1 and itself. The number 63 is composite because it is divisible by 3, 7, 9, and 21. Therefore, 63 is the wrong term that does not belong to the prime number sequence.
