Fruit Flies Normally Produce Two Types of Antimicrobial Peptides (Defensin

Fruit flies normally produce two types of antimicrobial peptides (defensin and drosomycin) .Mutant fruit flies were generated that produced no antimicrobial peptides,defensin only,or drosomycin only.Wild-type flies and the mutant flies were then tested for survival after infection with Micrococcus luteus bacteria.What statement about these data is true?

A) Drosomycin likely protects fruit flies by activating an adaptive immune response.
B) Drosomycin and defensin are equally effective at protecting fruit flies from the bacterial infection.
C) Defensin likely protects fruit flies by activating an innate immune response.
D) After five days,greater than 90% of mutant fruit flies are dead.
