Correct option is B
The optimum average temperature requirement for the ripening of wheat is typically between 14–16°C. During this temperature range, wheat grains mature properly, ensuring a good quality yield.
Wheat requires cooler temperatures during the ripening stage for optimal development.
Higher temperatures (above 20°C) can cause early ripening with potential yield loss.
Low temperatures (below 10°C) can delay ripening and negatively affect grain formation.
