Answer 2

Option (d) is the right answer.

Parthenocarpic tomato fruits can be produced by treating the plants with low concentrations of gibberellic acid and auxins.

It's due to the following reasons :

- Stimulation of parthenocarpy is done by spraying some vital plant hormones onto their flowers which transforms those flowers into fruits.

- The plant hormones which are used are auxin , gibberellins , cytokinin etc.

- After these hormones are sprayed they violate the process of fertilisation and induce the phenomenon of maturing without fertilisation into the ovaries.

- This process of growing fruits without fertilisation is known as artificial parthenocarpy or parthenogenesis.
