Q: Which of the following pairs is NOT a pair of twin primes?
  • A. 11, 13
  • B. 71, 73
  • C. 131, 133
  • D. 191, 193
Correct Answer: Option C - From option (c), Factor of 131 = 131, 1 and Factors of 133 = 1, 7, 19, 133. Hence, this pair is not a pair of twin primes.
C. From option (c), Factor of 131 = 131, 1 and Factors of 133 = 1, 7, 19, 133. Hence, this pair is not a pair of twin primes.

Explanations:

From option (c), Factor of 131 = 131, 1 and Factors of 133 = 1, 7, 19, 133. Hence, this pair is not a pair of twin primes.
