How can seed diversity help reduce climate risk in agriculture?
Answer and explanation
Correct answer: Different varieties increase the chance of survival under different weather stresses
Seed diversity means growing or preserving more than one variety of a crop. Different varieties may differ in their tolerance of heat, drought, excess rain, pests or changing sowing conditions. If one variety performs poorly during unusual weather, another may survive and produce at least some yield. This spreads risk instead of making the whole harvest depend on one type of seed. It can therefore support adaptation and improve the chances of food and income security under uncertain climate conditions.
Option A is correct because it states that different varieties may survive different weather stresses. The word “may” is important: seed diversity does not guarantee success in every season, but it increases available options and reduces dependence on one response. Options B, C and D make absolute or unrelated claims. Thus A best explains how diversity can reduce climate risk.
