Statement I says that Mitosis is also called the reduction division, which is false. Mitosis is actually called the equational division because the daughter cells produced have the same number of chromosomes as the parent cell.

Statement II says that Mitosis takes 30 minutes to 3 hours to complete, which is true. The time required for mitosis to complete is species-specific and depends on factors such as tissue type and temperature.

Option 4 is the correct answer.
