The correct option is D placenta
The ovary of the gynoecium produces one or more ovules. Each ovule is attached to the placenta by a slender stalk called funicle.
In plant ovules, the chalaza is located opposite the micropyle opening of the integuments. It is the tissue where the integuments and nucellus are joined. Nutrients from the plant travel through conducting tissue in the funiculus and outer integument through the chalaza into the nucellus.
