It is possible to produce seedless tomato fruits by

A

applying trace elements in tomato fields

B

spraying mineral solution on plants

C

spraying hormones on flowers

D

applying fertilizers containing radioactive elements

Correct Answer: Option C

Explanation

1. Producing seedless fruits, like tomatoes, involves a process called parthenocarpy, where fruit develops without fertilization. 2. This can often be induced artificially by the application of plant hormones. 3. Spraying hormones, such as auxins or gibberellins, onto the flowers can stimulate the ovary to develop into a fruit even in the absence of pollination and fertilization, resulting in seedless varieties. 4. Applying trace elements, mineral solutions, or radioactive fertilizers are not standard methods for inducing seedlessness in tomatoes.
