To solve this problem, we need to understand how offsets are produced. Offsets are a type of vegetative propagation.$\newline \bullet$Offsets are small, complete daughter plants that are genetically identical to the parent plant. They are produced asexually.$\newline \bullet$Asexual reproduction in plants typically involves mitotic divisions, which allow for the production of genetically identical offspring.$\newline \bullet$Mitotic divisions result in the formation of new cells that are clones of the parent cell, maintaining the same genetic material.$\newline$Therefore, offsets are produced by mitotic divisions.$\newline$This corresponds to Option 2.
