When chiasmata can first be seen in cells using a microscope, the following processes has most likely occurred in prophase I.
<h3>When chiasmata can first be seen in cells using a microscope?</h3>
Recombination can occur at any two chromatids within this tetrad structure.
 Crossovers between homologous chromatids can be visualized in structures known as chiasmata, which appear late in prophase I.
Thus, option "C" is correct, Prophase I.

Interphase: Chromosomes duplicate, and the copies remain attached to each other.
Prophase: In the nucleus, chromosomes condense and become visible. Spindle fibers begin to form.
Prometaphase: The nulcear membrane breaks apart, and the spindle starts to interact with the chromosomes.
Metaphase: The copied chromosomes align in the middle of the spindle.
Anaphase: Chromosomes separate into two genetically identical groups and move to opposite ends of the spindle.
Telophase: Nuclear membranes form around each of the two sets of chromosomes, they begin to spread out, and the spindle begins to break down.
Cytokinesis: The two cells split into two daughter cells, each with the same number of chromosomes as the parent cell.
