Show answer and explanation
Correct answer: (b) at an angle with substratum
Explanation
The malaria-carrying female Anopheles rests with its body held at an angle (about 45°) to the substratum.
The female Culex rests with its body parallel to the surface, distinguishing the two.
Anopheles transmits malaria, while Culex spreads filariasis and West Nile virus.
