Which one of the following is a micronutrient of plants?
This outcome reflects plant biotechnology, where photosynthetic engineering and nutrient pathways support biofortification. Option A captures this correctly because it supports metabolic engineering in crops, consistent with textbook descriptions and experimental observations in plant biology.
Ref: Taiz et al., Plant Physiology and Development, 6th Edition, Chapter 7, Photosynthesis, discusses light reactions, Calvin cycle and metabolic engineering examples like Golden Rice providing insight into plant biotechnology.
