A) Prime numbers: 13, 5, 37, 29, 2, 79, 5, 97, 27 (Note: 27 is not prime — correction: Prime numbers are 13, 5, 37, 29, 2, 79, 5, 97. 27 is composite.)
Actually, let’s correct and list only true primes:
A) Prime numbers: 13, 5, 37, 29, 2, 79, 97
B) Composite numbers: 96, 89, 45, 61, 41, 72, 84, 73, 92, 79, 7, 21, 80, 17, 8, 97, 15, 83, 19, 62, 51, 11, 4, 23, 32, 67, 3, 49
Correction: Composite numbers are non-prime numbers >1.
So from B:
Composite numbers: 92, 21, 80, 8, 15, 62, 51, 4, 32, 49
C) Multiple choice questions:
1) Greatest prime number:
a) 74 → composite
b) 23 → prime
c) 49 → composite (7×7)
d) 31 → prime
→ Between 23 and 31, 31 is greater → Answer: d) 31
2) Smallest composite number:
a) 12 → composite
b) 59 → prime
c) 8 → composite
d) 43 → prime
→ Between 12 and 8, 8 is smaller → Answer: c) 8
Final corrected answers:
A) Prime: 13, 5, 37, 29, 2, 79, 97
B) Composite: 92, 21, 80, 8, 15, 62, 51, 4, 32, 49
C) 1) d) 31; 2) c) 8
