Can you please help me with the approach I should follow while attempting such long questions.
I took some 2 mins to settle down with D which was even wrong because I didn't pay attention to the later half of the sentence.

Can you please help me with the approach I should follow while attempting such long questions.

you should follow the same approach for questions of all lengths. there's no reason to do anything differently.

remember, if you're doing SC effectively, you'll be ignoring everything except a single issue at any given time.
if this is so, then the length of the sentence is irrelevant in the first place. (for a longer sentence, the only consequence is that you'll ignore more stuff at any given time.)
