|D||Use of bed nets for mosquito|

This question must be interpreted correctly to go for the answer. The question is asking for a deliberate method of vector control, so any option where active effort is being made to control the vector would be the answer of choice. Some imp facts about malaria control:
a. The success of the malaria control programme stems from the strategy of bed net distribution, where large fractions of the population were locally covered at the village level, ensuring the reduction in transmission, even leading to local elimination in some islands.
b. An efficient bed net programme needs to cover a large proportion of the population in order to ensure that both sources (e.g., asymptomatic people) and sinks (e.g., pregnant women and young children) of infection are effectively covered.
c. The erroneous targeting of transmission groups for control can exacerbate the conditions for transmission.
d. Additionally the goal should be to cover as much of the population present in the endemic setting as possible, retaining traditional practices (e.g., voluntary work) for the exchange of goods when mainstream means of commercialization are not enough to achieve such a goal.
e. In Vanuatu, special care was taken to address these factors by implementing a strategy where children under five years of age, their mothers and pregnant women received free nets.
