Pyrethrin
C)
Malathion
D)

Correct Answer :   Pyrethrin

Pyrethrum : a natural insecticide that will 'knock down' most insects, but unless something like piperonyl butoxide is added, the insects will not be killed. Pyrethroids - are the synthetic versions of pyrethrum and they are effective against most insects. However, they do last longer in the environment than pyrethrum.
