Solution

The correct option is B 400 to 500
Just after copulation, female Bombyx mori, starts egg laying, which is completed in 1-24 hours. One moth lays 400 to 500 eggs depending upon the climatic conditions and the supply of the food. When first laid, all eggs are lemon-yellow. After three days, they will turn white if they are infertile, or turn black if they are fertile. Hence, option B is correct.
