The original sentence uses two unnecessary commas. The phrase &quot;only active at night&quot; is a nonessential element that describes the butterfly and can therefore be set off with commas. &quot;And it had a unique, very complex mating ritual&quot; is an independent clause, which cannot be joined to the main clause with just a comma. This creates a comma splice. The only option that removes the unnecessary commas and corrects the comma splice is choice C.</p>","correct_answer":["C"],"has_media":false,"has_mathml":false,"has_table":false,"source_created_at":null,"source_updated_at":null,"options":[{"label":"A","content_html":"<p>and it was only active at night, and it had a unique, very complex mating ritual.</p>","ord":0},{"label":"B","content_html":"<p>being only active at night and having a unique, very complex mating ritual.</p>","ord":1},{"label":"C","content_html":"<p>only active at night, and it had a unique, very complex mating ritual.</p>","ord":2},{"label":"D","content_html":"<p>active only at night, and it had a unique, very complex mating ritual.</p>","ord":3}],"attribution":{"source_id":"opensat","source_name":"OpenSAT community question bank","rights_holder":"OpenSAT contributors","canonical_url":"https://github.com/Anas099X/OpenSAT","retrieved_from":"https://pinesat.duckdns.org/api/questions","attribution":"Reading and Writing practice questions from the OpenSAT community question bank, whose licence permits free use of the database.","disclaimer":"OpenSAT items are community-written or AI-generated practice material, not official College Board questions; quality varies.","license":"OpenSAT LICENSE.md: the database may be used freely, including commercially, without restriction.
