Solution

The correct option is D Inferior
The shape and growth of the thalamus determine the position of the ovary.
A. In the superior ovary, the thalamus is swollen or dome-shaped. Such flowers are called hypogynous.
B and C. In the half-superior or half-inferior ovary, the thalamus is flattened. Such flowers are called perigynous.
D. In the inferior ovary, the thalamus is cup-shaped and grows over to fuse with the ovary. Such flowers are called epigynous.
Hence, the correct answer is 'Inferior'
