Explanation:

- The development of a fruit without fertilization is called parthenocarpy.

- Option 1: Parthenocarpy

- This is when fruits form without seeds because they develop without fertilization.

- Common in bananas, seedless grapes, etc.

- Option 2: Gametogamy

- This is not a standard botanical term related to fruit development.

- Option 3: Hybridogenesis

- Refers to a type of reproduction mostly in animals, not related to fruit formation.

- Option 4: Apomixis

- Involves seed formation without fertilization, leading to offspring that are clones of the parent. Not the same as parthenocarpy, as parthenocarpy leads to seedless fruits.

- Correct answer is Parthenocarpy (Option 1).
