Which outcome occurs when stellar nucleosynthesis exhausts lighter elements forming iron?

💡 Explanation

Fusion consumes lighter elements until iron-56 which exhibits the greatest nuclear binding energy per nucleon: therefore, further fusion demands energy input rather than releases it, because core collapse ensues leading to a supernova, rather than stability.
