Though now eaten in large quantities around the world and harmless, the tomato is a member of the generally toxic nightshade family, including belladonna, and was once thought to be poisonous itself as a result.
Major problem is parallelism between eaten in large quantities around the world and harmless in A, B, C & E
SO D is answer

Apart from this C & E has meaning issue
C fails to show the contrast by removing though
D conveys the contrast the other way around even though it is harmless in place of Though now eaten
in A & B poisonous itself doesn't sound okay
Hence its D again


A) Though now eaten in large quantities around the world and harmless, the tomato is a member of the generally toxic nightshade family, including belladonna, and was once thought to be poisonous itself as a result.
B) The tomato, though now eaten in large quantities around the world and harmless, is a member of the generally toxic nightshade family, which includes belladonna, and it was therefore once thought to be poisonous itself.
C) Once thought to be poisonous itself, the tomato is harmless and now eaten in large quantities around the world, and is a member of the generally toxic nightshade family, including belladonna.
D) Though now eaten in large quantities around the world and known to be harmless, the tomato was once considered poisonous because it is a member of the generally toxic nightshade family, which includes belladonna.
E) A member of the generally toxic nightshade family, including belladonna, the tomato was once considered poisonous even though it is harmless and now eaten in large quantities around the world.

A) Though now eaten in large quantities around the world and harmless, the tomato is a member of the generally toxic nightshade family, including belladonna, and was once thought to be poisonous itself as a result.

_________________

The original sentence contains a lot of clauses in a confusing order. We need to find an answer choice that rephrases the sentence in a clear and concise manner. Also, the phrase "though now eaten in large quantities around the world and harmless" contains two elements that are not parallel. Moreover, "including belladonna" is incorrect left dangling. It should be "which includes belladonna." Finally, "itself" could refer either to "tomato" or to "belladonna".

(A) This choice is incorrect as it repeats the original sentence.

(B) The pronoun "it" is ambiguous as it could refer either to "the nightshade family" or "belladonna" or "tomato." Additionally, the phrase "though now eaten in large quantities around the world and harmless" contains two elements that are not parallel.

(C) The phrase "including belladonna" does not properly modify anything.

(D) CORRECT. The opening phrase contains the two parallel elements "eaten in large quantities . . ." and "known to be harmless." The phrase "which includes belladonna" correctly modifies the "nightshade family." Finally, the pronoun "it" unambiguously refers to the tomato.

(E) The phrase "including belladonna" does not properly modify anything.

Though now eaten in large quantities around the world and harmless, the tomato is a member of the generally toxic nightshade family, including belladonna, and was once thought to be poisonous itself as a result.[/u]

Here we have conditional clauses.

(A) Though now eaten in large quantities around the world and harmless, the tomato is a member of the generally toxic nightshade family, including belladonna, and was once thought to be poisonous itself as a result.
use of though in first clause to differentiate second clause is not appropriately conveys the meaning.

(B) The tomato, though now eaten in large quantities around the world and harmless, is a member of the generally toxic nightshade family, which includes belladonna, and it was therefore once thought to be poisonous itself.
'though now eaten in large quantities around the world and harmless' is not acting as modifier of Tomato

(C) Once thought to be poisonous itself, the tomato is harmless and now eaten in large quantities around the world, and is a member of the generally toxic nightshade family, including belladonna.
itself is inappropriate. Also 1st and 2nd clause is not differentiating proper meaning.

(D) Though now eaten in large quantities around the world and known to be harmless, the tomato was once considered poisonous because it is a member of the generally toxic nightshade family, which includes belladonna.
differentiation is perfectly appears between 1st and 2nd clause.KEEP

(E) A member of the generally toxic nightshade family, including belladonna, the tomato was once considered poisonous even though it is harmless and now eaten in large quantities around the world.
D appears better
