May I point out the major mistake in options D and E.
D and E saymore 'fuel efficient small cars' , meaning that technology is helping make more cars (that are fuel efficient)
C corrects this issue,small cars that are more fuel-efficient . This suggests correctly that technology is helping make small cars that are actually more 'fuel efficient'.
Option A and B clearly have the ambiguous 'their' pronoun issue. Hence the answer is C.
Please give Kudos if this helps you.
