Show answer and explanation

Correct answer: (D) Malarial fever, also transmitted by mosquitoes, has increased this year.

Explanation

Imported cases, improved reporting and better diagnosis can increase recorded dengue independently of local mosquito-control failure. A rise in another mosquito-borne illness instead supports the concern rather than supplying an alternative explanation. Thus **D** does not contradict the conclusion; this evaluates the passage’s argument.
