Solution

The correct option is D Flacherie
Flacherie is a disease of silkworms, caused by silkworms eating infected or contaminated mulberry leaves. Flacherie infected silkworms look weak and can die from this disease. There are two kinds of flacherie : infectious (viral) flacherie and non-infectious (touffee) flacherie. Viral flacherie is ultimately caused by infection with Bombyx mori infectious flacherie virus, Bombyx mori densovirus etc. Hence, option D is correct.
