In an experiment, the right forepaw of a developing mouse embryo is examined. The tissue and cellular structure are microscopically analyzed with histology at several developmental time points.

In the earliest time point, a population of cells located between the future digits of the paw is found to undergo growth-arrest and then subsequent cell death.

Are the cells MOST likely undergoing apoptosis or necrosis, and which of the following provides an explanation for why?

A

Apoptosis, as this is a normal step in development.

B

Apoptosis, as the limb must have been malformed.

C

Cellular necrosis, as this is a normal step in development.

D

Cellular necrosis, as the limb must have been malformed.
