Let's call the certain number "x".

The problem states:

68 - 8x = 4

To solve for x, we need to isolate it on one side of the equation.

First, we can simplify the left side by subtracting 68 from both sides:

-8x = -64

Next, we can solve for x by dividing both sides by -8:

x = 8

Therefore, the certain number is 8, which is answer choice B.
