Use of "Their"

Its a hanging modifier. Original sentence doesn't clearly indicate whom do we refer to with "their"

C doesn't use "Their", and hence the correct option.

Hi TomB and other friends,

Let's analyze original sentence and all the answer choices one by one. There are two mistakes in original sentence.
1. For the idiom more x than y, X and Y should be parallel. Here X = fuel-efficient and Y = at any time in their production history(lets say 1990). Which are not parallel. Consider right usage ex : My car is more fuel efficient than your car. OR My car is more fuel efficient than powerful.
2. Usage of pronoun 'Their". Their can refer to both "cars" and "manufactures" so there is no clear antecedent for "their".

A is wrong because of above reasons.
B is wrong because : 1. Usage of "they" and " Their"
C is still has pronoun issue but meaning wise it is best . It is comparing small cars with those old cars. Lets have same substitution
Today’s technology allows manufacturers to make small cars that are more fuel-efficient than those at any other time in production history.
Today’s technology allows manufacturers to make small cars that are more fuel-efficient than those at 1990.
D We can prefer C over D also for modifier reason : D has two continuous modifier "more fuel-efficient" and "small" intended to modify cars. In c we don't have continuous modifier, that is better. Usage of "their" again leading to ambiguity along with "those"
E. It again has 2 modifier continuously.

I hope my explanation helped. If indeed please give me kudos.
Giving Kudos is a decent way to say Thanks.

I have another observation on option B.
"small cars that are more fuel-efficient than they were at any time in their"..

This sentence is more like " they are more happier than they were" or " I am more athletic than I was..."... here i am comparing a mood/state of myself of the past with the present.

But how can a small car be more fuel efficient now than it was?
A small car today is more fuel efficient than a small car t any other time. So "those" is a better pronoun than "they".

This observation may not matter in the given example. But this will help if the last word (their) is omitted from option B.

5) 53. Today’s technology allows manufacturers to make small cars more fuel-efficient now than at any time in their production history.
A. small cars more fuel-efficient now than at any time in their
B. small cars that are more fuel-efficient than they were at any time in their
C. small cars that are more fuel-efficient than those at any other time in
D. more fuel-efficient small cars than those at any other time in their
E. more fuel-efficient small cars now than at any time in

A) Small cars are compared with time
B) Same as A
C) It is correct
D) Now, In D the cars are compared with cars with the help of those, but “at any other time in their history” also includes the time in which manufacturers made these small efficient cars. You cannot compare these small cars with themselves.
There is one more error. The question stems wants to say small cars that are more efficient. So according to the past, today’s small cars are more efficient. But, if you say "more full-efficient small cars", it means you are comparing a number of cars. That the number of fuel efficient small cars is more than other cars.
E) Same as above

Hope it helps:)
