Why isn't A the right answer.
Official Explanation:
Answer – E
(A) Since the subject of the clause before the comma is
polarised sunglasses, these should, to maintain parallelism, ideally be the subject of the clause after the comma as well. You cannot use
these on its own; it needs to be followed by
glasses. The use of
their is ambiguous.
(B) The use of too many
their’s is ambiguous and awkward. Also, the singular
coating does not agree with the plural
make.
(C) The singular pronoun
it cannot refer to the plural
sunglasses.
(D) The phrase
because of the coating on these glasses is awkward and wordy. Also, the infinitive
to read is preferred to the gerund
reading.
(E) The correct answer.
