Which option is an example of mechanical controls in IPM?

Explanation:
Mechanical controls in IPM are physical methods that directly reduce pest populations without using chemicals. An example is using barriers to keep pests away from crops, traps to capture them, and handpicking to remove individuals by hand. These methods act through direct, non-chemical means, providing immediate pest reduction. Pesticide application uses chemicals, crop rotation is a cultural practice to disrupt pest life cycles, and releasing natural enemies is a biological control strategy. Because barriers, traps, and handpicking are all physical actions that directly prevent or remove pests, they exemplify mechanical IPM controls.
