Question

in the 1800s, the irish solved the problem of feeding a growing population by planting potatoes. specifically, potatoes are propagated by cutting potatoes into pieces, each piece containing an eye that sprouts into a new plant. however, the potato crop was devastated by potato blight and because ireland was so dependent on the potato, one in eight irish people died of starvation in the 1840s. the basis for the devastation of the potato crop was
a asexual reproduction and genetic sameness.
b not focusing on just one species of potato.
c choosing a staple crop that was susceptible to blight.
d planting a crop that did not tolerate the maritime climate.

Explanation:

Potatoes were propagated asexually by cutting pieces with eyes. Asexual reproduction leads to genetic sameness among plants. When potato - blight struck, due to the lack of genetic diversity (because of asexual reproduction), the entire crop was vulnerable and devastated.

Answer:

A. asexual reproduction and genetic sameness
