Important: When a sentence begins with a with noun modifier (as it does in the above sentence), stop at the comma and ask the question that the modifier raises.

So, once we read, Responding to growing demand for high-end vehicles, we should stop and ask . . .

"Who or what is responding to growing demand for high-end vehicles?"

If the sentence is properly constructed, the part that immediately follows the comma will answer that question in a logical manner.

Reading on we get...

A the interiors...
The interiors are responding to growing demand?
Makes no sense. ELIMINATE A

B the interiors...
The interiors are responding to growing demand?
Makes no sense. ELIMINATE B

C auto makers ...
Makes sense. KEEP C

D the interior...
The interior is responding to growing demand?
Makes no sense. ELIMINATE D

E auto makers ...
Makes sense. KEEP E

Now re-check C: auto makers have installed interiors in the newest models that are so luxurious that they sell
It's not clear what they refers to.
ELIMINATE C

Answer: E
