In this question, we are asked to identify the odd one out based on crop season.

Option 1: Rice - Rice is typically grown in wet or flooded conditions, and it requires a long growing season.

Option 2: Wheat - Wheat is a cool-season crop and is typically grown during the winter or early spring.

Option 3: Maize - Maize, also known as corn, is a warm-season crop that is usually planted in the spring and harvested in the late summer or early fall.

Option 4: Cotton - Cotton is a warm-season crop that is usually planted in the spring and harvested in the fall.

The odd one out based on crop season is option 2, Wheat, as it is the only cool-season crop in the given options. The other three options, Rice, Maize, and Cotton, are all warm-season crops that are planted and harvested during the warmer months.
