Option 3 : 3

The phrase ‘it has 20 times the ability heat-trapping’ is grammatically incorrect making option 3 as the correct answer to mark the error of the sentence.

The third part of the sentence lacks the preposition between the words ability and heat-trapping forming no relationship between them. Thus, use of ‘of’ must be used between them to correct the error.
