It is C. Compound sentence. This is because it is far from simple, and even thought it might seem as a run on sentence, it is not, as run on sentences are sentences connected with a comma, yet this one is connected with a semi-colon, which is a correct way of connecting sentences.
<span>A </span>simple sentence<span> contains the basic element
that make a sentence and that is a subject and a predicate. The sentence must
one independent clause and expresses one idea. Compound sentences other hand contains
two ideas. In the sentence: </span>My sister works with clay; she
molds and paints it. It is a compound sentence since there are two ideas, that
is, two subject ‘sister’ and ‘she (basically still the sister)’ and two
predicates ‘works with clay’ and ‘molds and paints it’.
<span> </span>
Edit: I just now realised that the person who asked the question literally said, "the answer is love", I obviously don't pay attention lol. Have a nice day!
The twin getting a C is using a fixed mindset. Just because your twin gets a better grade does not make you dumber it means you may need a different approach at what you are doing.
