The right option is C: prophase

Prophase is the phase of the cell cycle Ryan is observing.

Prophase is the first stage of mitosis during which the chromatin condenses to form the visible chromosomes. Also, a structure known as mitotic spindle which is composed of long proteins (microtubules) begin to form from the opposite ends of the cell (centrosomes) and a part of the nucleus where ribosomes are produced disappears during this phase.

madam [21]
The proteins are called Histone proteins. Chromosomal DNA is packaged such that the strands of DNA are wound around histone proteins and fold into complex ways to form chromosomes. The histone proteins are positively charged proteins that strongly adhere to negatively charged DNA and form complexes called nucleosomes. Each nucleosome is composed of double-helical DNA wrapped.
