Answer:
The right ventricle pumps the blood with less oxygen to the lungs through the pulmonary valve. The left atrium gets the blood with the most oxygen from the lungs and pumps it to the left ventricle through the mitral valve.

Explanation:
Apoptosis is a genetically controlled process taking place in the multicellular organisms which is marked with the self-destruction called or programmed cell death.
During apoptosis various physiological and morphological changes take place in the cell such as fragmentation of nuclear DNA, nucleus, shrinkage of cell and mRNA decay.
Since apoptotic cell undergoes cell death which is genetically controlled or programmed by the genes, therefore, apoptosis is known as the programmed cell death.
Thus, Option-C is the correct answer.
