Nothing. D and E are both internally correct, E slightly more concise which is why it's probably the right answer.

Is it really so? 'which' normally refers to the preceding noun/pronoun.

Please shed some light on it.

Think as explained correctly the subject "effects of Bacterial deterioration" is plural and hence cannot be clubbed with a singular verb "includes". Thus D stands eliminated.
Apologies if you already spotted it.

The leader of the Cahona silverback Gorillas, which are usually distrustful of strangers, is actually a small but clever Ourang Outang.

The subject of the main clause is the singular X "the leader", and correctly agrees with a singular verb "is".

However, the relative clause beginning with "which" modifies the noun directly before it - in this case the "Cahona silverback Gorillas". This is a Plural noun, and thus agrees with a plural verb "are".

The same thing happens D: the relative clause beginning with which modifies the singular noun "bacterial deterioration", so the singular verb "includes" is grammatically correct. I agree that logically, it makes more sense for the effects of deterioration to include spoilage of food, corrosion of metals, decay, etc. than for the deterioaration itself to include these phenomena - another point in favor of E instead of D, besides conciseness. But grammatically, there's no real SVA problem with D.
