Answer: Second Option

b > 49

Explanation:

We have the following expression:

log_7(b) > 2

We have the following expression:

To solve the expression, apply the inverse of
log_7 on both sides of the equality.

Remember that:
$b ^ {log_b (x)} = x$

So we have to:

7^(log_7(b)) > 7^2

b > 7^2

b > 49

The answer is the second option
