Question

which of the following has a high mineral content in green, leafy vegetables?
○ calcium
○ iron
○ fiber
○ vitamins

Explanation:

Green, leafy vegetables (like spinach, kale) are known to be rich in iron. Calcium is also present but iron is a key mineral with notable content here. Fiber is a carbohydrate (not a mineral), and vitamins are organic compounds (not minerals), so we eliminate those. Among the mineral options (Calcium, Iron), Iron is highly associated with high content in leafy greens.

Answer:

B. Iron (assuming the options are labeled as A. Calcium, B. Iron, C. Fiber, D. Vitamins; if labels differ, adjust but the correct option is the one with Iron)
