we are comparing cars in the sentence............than is used for comparison and "those" over here refers to the cars which used to be built earlier.............

The option C correctly uses "than those at any other time in production history". The other options have "in their production history" which is wrong.

C is the right answer.

The important issue with those is that when we are construing a sentence we have to make sure apples are being compared to apples and oranges are being compared to oranges.

In the original sentence the efficiency of cars is being comapred to "any time in their production history." This is WRONG. We want to compare cars built now with cars built in the PAST. By adding THOSE we know logically that the comparison is cars now and cars in the past.

Why is the comparison when THOSE is added? Simple because those in the sentence refers to the cars. With option C new efficient cars is being compared with older cars that are less efficient. So vola!
