Answer: B
Explanation:
Seasons don't have capitalizations. Spring, summer, fall, and winter should all be lowercase in a sentence except for the start of one (like this sentence). Therefore, B is the only correct sentence.
A subordinate clause, dependent clause or embedded clause is a clause that is embedded within a complex sentence. For instance, in the English sentence "I know that Bette is a dolphin", the clause "that Bette is a dolphin" occurs as the complement of the verb "know" rather than as a freestanding sentence.
