Step-by-step explanation:
(D) Synthetic textiles developed during World War I reduced demand for cotton.
Synthetic textiles, such as nylon and rayon, were developed during World War I and became increasingly popular in the 1920s and 1930s. These materials were cheaper and more durable than cotton, and as a result, demand for cotton fell sharply. This had a major impact on cotton farmers, as they struggled to sell their crops and make a living.
