A. Three
B. Four
C. Nine
D. Six

Answer 1

In flowering plants, an ovary is a part of the female reproductive organ of the flower also known as the gynoecium. Specifically, it is the part of the pistil which holds the ovule(s), and is located above or below or at the point of connection with the base of the petals and sepals.

Complete step by step answer: A flower that has an inferior ovary which lies below the attachment of other floral parts is termed as epigynous. Among china rose, mustard, bitter gourd, brinjal, lupin, sun hemp, guava, banana, chilli, Rrose, aloe and tulip, plants that have epigynous flowers include guava, bitter gourd and banana. When a half-inferior ovary in a flower is embedded or surrounded by the receptacle. Such flowers are termed perigynous or half-epigynous. This occurs in flowers of the family Lythraceae, which includes the crape myrtles. A half-inferior ovary has nearly equal portions of ovary above and below the insertion point.
On the other hand, a superior ovary is an ovary attached to the receptacle above the attachment of other floral parts. A superior ovary is found in fleshy fruits such as true berries, drupes, etc. A flower with this arrangement is described as hypogynous. Examples of this ovary type include the legumes.
Hence, the correct answer is option A.

Note: The terminology of the positions of ovaries is determined by the insertion point, where the other floral parts (perianth and androecium) come together and attach to the surface of the ovary. If the ovary is situated above the insertion point, it is superior; if below, it is regarded as inferior.
