Correct answer: B. 2
Explanation: Mitosis produces 2 genetically identical daughter cells, each with the same chromosome number as the parent cell.
The cell cycle: G1 (growth and preparation), S (DNA replication, chromosome number stays 2n but DNA content doubles), G2 (final checks before division), and M (mitosis itself) - together, G1+S+G2 make up interphase.
Concept context
Mitosis and meiosis: how cells divide for growth, repair, and reproduction.
