Why are resistant plant varieties beneficial?

1. They require more water

2. They minimize pest resistance

3. They reduce the risk of disease

4. They grow faster

The correct answer is: They reduce the risk of disease

Resistant plant varieties are beneficial primarily because they reduce the risk of disease. By being bred or selected for specific traits that confer resistance, these plants are less susceptible to infections by pathogens such as fungi, bacteria, and viruses. This resistance not only helps maintain the health of the plants, but it also minimizes the need for chemical treatments, which can be both costly and environmentally damaging. Moreover, when plants are healthier and less prone to disease, they can yield more produce and require less management from growers, leading to more sustainable agricultural practices. While there might be some connection with pest resistance, the primary focus on disease risk highlights the vital role these varieties play in protecting crops. Additionally, while faster growth and water requirements could potentially contribute to the overall success of a plant, they are not inherently linked to the concept of "resistance" that the question addresses.
