Organochlorine pesticides were widely used in agriculture; however, due to their high toxicity and persistence in the environment, they were banned. Consider the application of 500 g of an organochlorine pesticide to a crop and that, under certain conditions, the half-life of the pesticide in the soil is 5 years. The mass of pesticide over 35 years will be closest to (A) $3.9 \mathrm{~g}$. (B) $31.2 \mathrm{~g}$. (C) $62.5 \mathrm{~g}$. (D) $125.0 \mathrm{~g}$. (E) $250.0 \mathrm{~g}$.
