Question

human consumption is diminishing fish and shellfish populations so the world wildlife federation is advocating for stricter limitations on fishing. choose 1 answer: a no change b populations, so c populations d populations,

Explanation:

When connecting two independent clauses ("Human consumption is diminishing fish and shellfish populations" and "the World Wildlife Federation is advocating for stricter limitations on fishing"), a comma and a coordinating conjunction (in this case, "so") are needed. Option B adds the comma before "so" which is the correct usage. Option A has no comma (incorrect as it creates a run - on sentence), Option C removes the conjunction which breaks the logical connection, and Option D only has a comma (a comma splice, incorrect).

Answer:

B. populations, so
