• A. $2.2$ meter
• B. $1.2$ meter
• C. ${10}^{-4}$ meter
• D. ${10}^{-6}$ meter

Answer 1

The correct option is D ${10}^{-6}$ meter

• In a mammalian cell nucleus is the largest organelle. The nucleus is the most important component of any cell.
• It is a site where the genetic material is present. It also plays a role in various cellular activities.
• The approximate size of the nucleus in a typical mammalian cell is 10 microns i.e. ${10}^{-6}$ meter.
  Hence, the correct answer is option D.
