Fertilizer salts causing symptoms

The correct answer is: Fertilizer salts causing symptoms

Fertilizer salts can cause various symptoms in plants, such as wilting, marginal burning, and dieback. The salts in the fertilizer can accumulate in the soil, leading to an imbalance in osmotic potential that affects the plant's ability to take up water and essential nutrients. This can result in the symptoms mentioned in option C. Therefore, option D is correct, as it accurately reflects the relationship between fertilizer salts and the symptoms they can cause.
