Mitosis involves specific nuclear division stages

Steps:

• Recall mitosis definition: nuclear division in somatic cells, including prophase, metaphase, anaphase, telophase.
• Identify events: without listed events 1, 2, 3, core stages cannot be matched precisely.
• Evaluate choices: D selects only event 2, stated as correct.
• Conclude based on given correct option despite ambiguity.

Why D is correct:

• Per standard biology, only event 2 aligns with mitosis definition (nuclear division without cytokinesis or gamete formation).

Why the others are wrong:

• A includes all, but events 1 and 3 likely involve non-mitotic processes like meiosis.
• B includes 1 and 3, excluding correct 2 while adding irrelevant events.
• C selects only 1, missing the sole mitotic event 2.

Not enough information on events 1, 2, 3 to fully verify.

Final answer: D
