Which element is responsible for making plants green?

Explanation:
Plants look green because of chlorophyll, the pigment in leaves. The color of chlorophyll comes from the magnesium atom at its center; this magnesium ion lets chlorophyll form properly and reflect green light. Nitrogen is essential for building chlorophyll, but it does not itself give the green color. The other listed nutrients don’t determine the leaf color the way magnesium does. Since magnesium is the element responsible for the green pigment in chlorophyll, it’s the correct concept to connect with the color, even though it isn’t one of the options given.
