Question Analysis  
This question involves finding natural numbers that satisfy both product and sum conditions, testing students’ ability to factor and add.  

Key Concept Explanation  
Factor pairs of 15: (1, 15), (3, 5).  
Check which pair sums to 8

Step-by-Step Solution  
1. List factor pairs of 15:  
 1 and 15: Product = 15, Sum = 16 (not 8).  
 3 and 5: Product = 15, Sum = 8 (matches).  
2. Options B (2 × 6 = 12 ≠ 15), C (4 × 4 = 16 ≠ 15), and D (sum = 16 ≠ 8) are incorrect.
