a) seed coat, endosperm, and embryonic plant.
b) seed coat, root, and stem.
c) eye, starch, and seed coat.
d) root system, starch coat, and seed coat.

Explanation:

1. Sexual propagation involves the union of male and female gametes, which occurs when plants are produced from seeds. Asexual propagation does not involve gamete fusion. Bisexual is a term related to having both male and female reproductive organs in one organism (not a type of propagation). Unsexual is not a standard term for plant propagation types.
2. A seed has a protective seed coat, endosperm (which provides nutrients), and an embryonic plant (which will grow into a new plant). The root and stem are parts that develop from the embryonic plant. An "eye" is related to vegetative propagation in some plants like potatoes (not a general seed part). Starch is a storage product (not a distinct part of a seed's structure as per the standard seed composition). Root system is what develops from the embryonic plant's root - part, not a part of the seed itself.

Answer:

1. C. sexual
2. A. seed coat, endosperm, and embryonic plant.
