In the following question, a sentence is divided into three parts, given in columns 1, 2 and 3. Match the statements from column 1 with those in columns 2 and 3 and find which of the following triplets given in the options make/s contextually and grammatically correct sense. "Only " before a triplet in an option means that only that one particular triplet is possible and no other triplet can be formed.

The correct pairs are ADI, BFH and CEG. ADI: 'A' introduces the subject 'tropical forests' which is world's ancient heritage and 'D' says that 'it is now slowly getting destroyed' and 'I' further talks about the rate at which it is getting destroyed. So, ADI forms a triplet. BFH: 'B' says 'every country should try' and what we should try is mentioned in 'F' i.e. 'protect and improve environment'. 'H' further discuss what else should be done i.e. 'protect forests and wildlife of the country'. Both 'F' and 'H' talk about the same idea i.e., 'protection'. So, BFH forms a triplet. CEG: 'C' says that 'the book explained something in detail' and what is explained is mentioned in 'E' i.e., 'effects of battle' and 'G' further tells about 'where the effects were seen' i.e., 'in the power struggle in India'. Moreover, 'for' (which is used for saying who or what is intended to get the benefit of something) indicates that some 'receiver' should be mentioned in the remaining part of the sentence. So, CEG forms a triplet. Hence, the answer is option b).
