The correct answer or option is cerebrum
The cerebrum, also called cortex is the largest part of the brain.
It is divided into four sections, called lobes and these are the frontal lobe,
the parietal lobe, occipital lobe and temporal lobe.
Front lobe helps in speech, reasoning, planning, movement ,
emotions and problem solving.
parietal lobe helps in orientation, and perception of stimuli and
movement.

Thus, the answer is spontaneous mutation.
The smallest complete living unit is the cell
Well , the student has not done justice to the question technically. He/she classified examples of cells entirely on other basis other than the observations seen on the prepared microscopic slides
<h3>Prepared microscopic slide</h3>
Prepared microscopic slides are set of slides that have been previously mounted by an individual who is a professional in the field.
It process involve immersing the sample ( either before or after fixation or mounting) in a dye solution and then rinsing and observing the sample under a microscope.
