Answer

Answer:

D. iron

Brief Explanation:

In a high - mass star life cycle, through a series of nuclear fusion reactions, elements are built up until iron is formed. Low - mass stars do not reach the stage of producing iron via fusion. Hydrogen, carbon, and helium are present in both low - mass and high - mass star life cycles at different stages, but iron is a key indicator of a high - mass star's advanced life cycle.
