Which statement accurately describes the relationship between cross-resistance and pesticide classes?

Explanation:
Cross-resistance happens when a pest population that’s resistant to one pesticide also shows resistance to other pesticides, often across different chemical classes, because the underlying resistance mechanism (like enhanced detoxification or changes at a target site) affects multiple products. That’s why the statement describing resistance across classes best fits the concept. It’s not about applying at label rate, it’s not limited to identical MOAs, and it isn’t caused by using multiple products together.
