I didn't understand the question at all, but I solved it using the SC principles.
B. Wrong: "since" (to indicate causality) is wrong in SC, ONLY in SC. "since" is valid in SC, if it refers to time.
C .Wrong: clauses cannot be located after "because of"
D. Wrong: "due to" means "caused by". It doesn't match in this sentence.
E. Wrong: Usually, a relative clause inside other relative clause is wrong.
I think I deserve kudos
