A sequence of thermonuclear fusion processes inside massive stars can continue to transform the nuclei of elements such as carbon and oxygen into heavier nuclei and also generate excess energy up to a limit beyond which no further energy-producing reactions can occur. The element that is produced when this limit is reached is

Question

Quizplus · Accepted Answer

Iron is the element produced when the limit is reached in the sequence of thermonuclear fusion processes inside massive stars. This is because iron has the highest binding energy per nucleon, making further fusion reactions energetically unfavorable without an external energy source.
