• C. Corn, beans, and squash; They were staple crops; This led to sedentary societies.
• D. Tomatoes, cucumbers, and squash.

Answer: (C)

The Three Sisters refers to a traditional intercropping system of corn, beans, and squash grown together. Each crop supports the others: corn provides a tall stucture for beans to climb, beans fix nitrogen to enrich the soil, and squash vines spread along the ground to suppress weeds and retain moisture. This combination yields a reliable, varied harvest that helped sustain larger, more sedentary communities. Other crop groupings listed don’t reflect this specific planting trio.
