Option 1: Large number of seeds of a single plant

Seeds of a single plant can indeed produce multiple identical plants. However, the time required for the plants to grow and develop from seeds can be relatively longer compared to other methods.

Option 2: Stem cuttings

Stem cuttings involve taking a piece of a plant`s stem and allowing it to root and grow into a new plant. This method can produce a large number of identical plants relatively quickly, as the cuttings already have the potential to grow into mature plants.

Option 3: Tissue culture technique

Tissue culture involves culturing small pieces of plant tissue in a laboratory under controlled conditions. This method can produce a large number of identical plants in a short span of time, as new plants can be grown from just a few cells of the original plant.

Option 4: Hydroponics method

Hydroponics is a method of growing plants without soil, using water and nutrient-rich solutions. While hydroponics can facilitate faster growth and increased yield, it does not necessarily guarantee the production of a large number of identical plants.
