Question

The hilum is a scar on the
(a) Fruit, where style was present
(b) Seed, where the micropyle was present.
(c) Seed, where funicle was attached
(d) Fruits, where it was attached to the pedicle.

Answer 1

Ovule is an integument megasporangium located in spermatophytes which grows into a seed after fertilization. An angiosperm ovule is usually an ovoid and whitish structure. It occurs inside the ovary where it's attached to a parenchymatous cushion called the placenta either singly or in a cluster.

Complete answer:
The hilum is a scar on the Seed, where the funicle was attached. In flowering plants, the ovule is found inside the portion of the flower called the gynoecium. The ovary of the gynoecium produces one or more ovules and eventually changes into the fruit wall. Ovules are connected to the placenta by a stalk-like structure called a funiculus (plural, funiculi) inside the ovary. The ovule is stalked. The stalk is called funiculus or funicle. The point of attachment of the body of the ovule with the funiculus is known as the hilum, which is found as a scar on a mature seed.
Different patterns of ovule attachment, or placentation, are often found among plant species, these include.
Apical placentation: The placenta is at the top of the ovary. Simple or compound ovary.
Axile placentation: The ovary is separated within the radial segments, with placentas in divided locules. Ventral sutures of carpels match at the center of the ovary. The placenta is along the combined margins of carpels.
Basal placentation: The placenta is at the bottom of the ovary on a projection of the thalamus.
Free-central placentation: Originated from axile as separations are absorbed, giving ovules at the central axis.
Marginal placentation: Simplest representation. There denotes a single elongated placenta on one side of the ovary, as ovules are connected at the fusion line of the carpel's margins.
Parietal placentation: Placentae on inner ovary wall inside a non-sectioned ovary, communicating to mixed carpal margins.
Superficial: Alike to axile, but placentae are on inner surfaces of the multilocular ovary

So, the correct answer is ‘Seed, where funicle was attached’.

Note:
In gymnosperms such as conifers, ovules are produced on the surface of an ovuliferous (ovule-bearing) scale, normally inside an ovulate cone. In the early extinct seed ferns, ovules were produced on the surface of leaves. In the most up-to-date of those taxa, a cupule (a modified branch or group of branches) enclosed the ovule.
