Hypogyny:
The thalamus is convex or conical. Gynaecium or
ovary develops at its top while stamens,
petals, and sepals are borne successively below. The
ovary or gynaecium is superior.
When the position of the ovary is below other floral organs of sepals, petals, and stamens, the ovary is called inferior and the flower is called epigynous. The thalamus, in this case, appears flattened.
A. Epigynous flowers have an inferior ovary.
B. Perigynous flowers have a half-inferior and half-superior ovary.
Hypogynous flowers have a superior ovary.

The Floral Arrangement
Floral arrangement refers to the position of the reproductive structures, including the ovary, stamens, petals, and sepals, in a flower. It plays a crucial role in determining the type of flower and its reproductive strategy. In this case, the floral arrangement is described as follows:
The Thalamus
The thalamus, also known as the receptacle, is the enlarged upper part of the flower stalk or pedicel. It is responsible for supporting and protecting the floral organs. In this particular floral arrangement, the thalamus is described as convex or conical in shape.
Location of the Ovary
The ovary, which contains the ovules and eventually develops into the fruit, is positioned at the top of the thalamus. This means that it is located above the other floral parts.
Borne Successively Below
Below the ovary, the stamens, petals, and sepals are arranged in a successive manner. This means that they are positioned one after the other, starting from the ovary and moving downwards along the thalamus.
Hypogamy and Ovary Superior
Based on the given description, the floral arrangement can be identified as hypogamous and the ovary is superior. Let's understand what these terms mean:
- Hypogamy: Hypogamy refers to the condition where the floral parts, such as stamens, petals, and sepals, are positioned below the ovary. This is the case in the given floral arrangement, where the ovary is located at the top of the thalamus, and the other floral parts are borne successively below it.
- Ovary Superior: When the ovary is positioned above the attachment point of other floral parts, it is referred to as a superior ovary. In this floral arrangement, the ovary is indeed superior as it is located at the top of the thalamus.
Therefore, the correct answer is option 'A,' which states that this floral arrangement is hypogamous and the ovary is superior.
