Correct Answer – Option 2 – asexual reproduction

Asexual reproduction is a method of reproduction where only one parent undergoes reproduction resulting in an offspring genetically identical to the clone. Commercially-important plants are often deliberately propagated by asexual means in order to keep particularly desirable traits such as flower color, flavor, etc. This technique of cutting the stem or branch of a parent and rooting this to grow another plant is known as grafting.

Sexual reproduction, gamete production and gene manipulation are methods of reproducing sexually with the involvement of 2 parents resulting in 1 or more offspring. Hence, options 1,3 and 4 are incorrect.
