B. Parthenocarpic berry
C. Drupe
D. Capsule

Answer 1

Hint: Banana (Musa acuminata) is one of the most popular fruits with high nutritional value belonging to kingdom Plantae. Banana is herbaceous monocot angiosperm which means a flowering plant.

Complete answer:Depending upon different characteristics all living organisms are classified into six kingdom classification which also tells us how these organisms are related to each other. There are 9 categories used for grouping of animals: Domain, Kingdom, Phylum or Division, Class, Order, Family, Genus, and Species. Animals with more common features are grouped as one species.
Banana belongs to the division Spermatophyta (‘Sperma’ means ‘seed’ and ‘phyta’ means ‘plants’). Members of this division have a sporophytic (having two sets of chromosomes) well-defined body. Division Spermatophyta is subdivided into two subdivisions: subdivision Gymnosperm (having naked seed i.e. seed is not covered by fruit) and subdivision Angiosperm (having covered seed i.e. seeds are covered with a protective layer).
Banana belongs to the subdivision Angiosperm. Most of the plants under angiosperm show sexual reproduction to develop fruit. But few plants develop fruit without fertilization. Sexual reproduction in plants; pollen from stamen is pollinated to the stigma that is the upper part of the female reproductive system. Fertilization of male gamete and egg in ovary takes place where male gamete in pollen on the stigma is transferred to ovary through style by pollen tube produced by pollen. After fertilization, the sporophyte is from which gives rise to a new flowering plant and the ovule develops into the seed of the plant and the ovary develops into the fruit. In some plants pollination and fertilization do not take place still fruit is formed, this process is called parthenocarpy. Here, the ovary itself produces few hormones to develop into a fruit. Such fruits that are formed without fertilization are called Parthenocarpic fruits.

Hence, the correct option is option B- Parthenocarpic berry.

Note: Banana is a berry because like berries a banana also has a protective exocarp and a middle fleshy mesocarp and an extreme inner portion that holds seeds is called the endocarp. In parthenocarpy, one of the hormones produced by plants (also known as phytohormone) is Auxin which helps in the formation of fruit without fertilization. Indole acetic acid has the same function as auxin but indole acetic acid is synthetic whereas auxin is naturally produced.
