...that their COMPLIANCE...IS PROTECTING adult sea turtles.
The subject of this relative clause is COMPLIANCE (singular).
Thus, the verb attributed to this subject (IS PROTECTING) must also be singular.
Eliminate A, C and D.

In E, laws TO REQUIRE turtle-excluder devices implies that the INTENTION/PURPOSE of the laws is TO REQUIRE turtle-excluder devices.
But the shrimpers' compliance with the laws IS PROTECTING the sea turtles RIGHT NOW.
To convey the intended meaning -- that the laws already ARE IN EFFECT -- a VERBing modifier is needed:
their compliance with laws REQUIRING turtle-excluder devices.
Eliminate E.

The correct answer is B.

Answers A, C and D can be ruled out because the verb forms "protect" and "are protecting" are plural whereas the subject "their compliance" is singular. The only choices that can be taken into consideration are answers B and E. E is unidiomatic because it incorrectly uses the phrase "laws to require". We could use this phrase to speak about the purpose of the mentioned laws. However, that is not the case in this sentence. B is correct.

A. requiring that turtle-excluder devices be on shrimp nets protect
B. requiring turtle-excluder devices on shrimp nets is protecting
C. that require turtle-excluder devices on shrimp nets protect
D. to require turtle-excluder devices on shrimp nets are protecting
E. to require turtle-excluder devices on shrimp nets is protecting

OA B
What protects the adult sea turtles? answer to this question is compliance which is SINGULAR.
Hence the plural forms "protect" (A and C) and "are protecting" (D) can be eliminated.
E is awkward because of the placement of "to infinitive".
Hence OA: B
