The correct answer is: C. They lack genetic diversity, making the entire crop susceptible to the same threats

Explanation:

In a monoculture, all plants are genetically similar or identical. This means if a pest or disease can infect one plant, it can easily spread to all the others. In contrast, diverse ecosystems have many different species and varieties, so a single pest or disease is less likely to harm every organism — diversity acts as a natural defense.
