"Prophase" is the one phase of mitosis among the choices given in the question are chromosomes first seen as a result of chromatin coiling. The correct option among all the options that are given in the question is the first option or option "A". I hope that the answer has come to your actual help.
Answer;
Prophase
Explanation;
-Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell divides once to form two identical cells.The major purpose of mitosis is for growth and to replace worn out cells.
-Mitosis is divided into five phases: Interpase, prophase, metaphase, anaphase and telophase.
-During prophase; the chromosomes condense into X-shaped structures that can be easily seen under a microscope. Each chromosome is composed of two sister chromatids, containing identical genetic information. The chromosomes pair up so that both copies of chromosome 1 are together, both copies of chromosome 2 are together, and so on.
-At the end of prophase the membrane around the nucleus in the cell dissolves away releasing the chromosomes.
