The development of the nematode worm C. elegans is highly reproducible. During development of the hermaphrodite, 1090 somatic cells are generated, but only 959 somatic cells are found in the mature adult. What is the MOST likely explanation for the change in cell number given its reproducibility?
A) inhibition of genes that stimulate cell division
B) activation of genes that inhibit cell division
C) apoptosis of cells during development
D) necrosis of cells during development
E) stochastic variations in cell division
