a. the cell prepares for mitosis.

Explanation:

Interphase is the period preceding any cell division, being of intense metabolic activity. During this period, there is the preparation for cell division (mitosis or meiosis), which involves the duplication of chromatin, the material responsible for controlling cell activity. All information existing throughout the DNA molecule is passed to the copy as if it were a photographic copy of the original molecule. Before long, each cell formed from the split will receive an exact copy of each chromosome of the split cell.

The two copies of each chromosome remain together for a time, joined by the common centromere, constituting two chromotids of the same chromosome. In interphase, the centrioles also duplicate.

i have to report this, it doesn't relate to biology

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
