What is indicated by yellowing veins within a leaf due to mineral loss?

  1. Susceptible/Pest Resistant

  2. Chlorosis

  3. Planting Specifications

  4. Mycorrhizae

The correct answer is: Chlorosis

This is a symptom of chlorosis, which can be caused by a lack of essential minerals, such as iron or magnesium, in the soil. Option A, susceptible/pest resistant, is not related to mineral loss and is therefore incorrect. Option C, planting specifications, does not provide an explanation for the yellowing veins. Option D, mycorrhizae, does not directly relate to mineral loss and is therefore not the correct answer.
