The correct option is (D) iteroparous; K -selected
Iteroparous organisms are the organisms that reproduce multiple times.
<h3>What is Semelparity and Iteroparity?</h3>
Semelparity and iteroparity are the two different reproductive strategies available to living beings.
Iteroparous species have multiple reproductive cycles throughout their lifetimes, while semelparous species have just one reproductive cycle before they die.
Death that occurs after reproduction is part of a bigger strategy in really semelparous animals that also entails maximizing reproduction at the expense of future survival.
There will always be some iteroparous individuals who die between their first and second reproductive episodes, but unless they exhibit symptoms of a state of programmed death after reproduction, they are not termed semelparous.
