B

Step-by-step explanation:

We want to solve the inequality:

First, we can add sec(x/3) to both sides:

Subtracting 4 from both sides yields:

And dividing both sides by 2 yields:

Therefore, we can graph the following two functions:

Where our solutions will be all the intervals where y = sec(x/3) is above the line y = -1.

B) is the right answer.
