• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

Answer: (C)

$3$

The Rule for 8:

If the last three digits of a whole number are divisible by $8$, then the entire number is divisible by $8$.

$6x2$ should be divisible by 8.

Put $x=3$ and we see that $632$ is divisible by 8 and gives $79$ as quotient.
