Correct answer: C. Let's analyze the pattern for each pair (first number, second number):
1.  7, 56: $7 	imes 8 = 56$
2.  13, 78: $13 	imes 6 = 78$
3.  9, 64: $9 	imes 7 = 63 
e 64$
4.  11, 132: $11 	imes 12 = 132$

In options A, B, and D, the second number is a multiple of the first number. Specifically, the second number is the first number multiplied by (first number + 1) or (first number - 1) or (first number + some constant). The pattern is not consistent across all, but 9, 64 clearly breaks the pattern of being a direct multiple or a simple arithmetic progression. The solution states $9 	imes 7 = 63 
e 64$. This is the odd one out.
