In the following question, a matrix of certain characters is given. These characters follow a certain trend, row-wise or column-wise. Find out this trend and choose the missing character accordingly.

6 6 8
5 7 5
4 3 ?

120

126 320

Option:
A. 4
B. 8
C. 12
D. 16
Answer: B . 8

Justification:

Clearly, (1st row) x (2nd row) x (3rd row) = 4th row.
In the first column, 6 x 5 x 4 = 120
In the second column, 6 x 7 x 3 = 126.
Let the missing number in the third column be y.
Then, 8 x 5 x y = 320 or y = 8.
