Match List-I (Embryo types) with List-II (Contributions of proembryonal cells) and select the correct answer:

List-I	List-II
a. Onagrad type	1. The basal and terminal cells, both contribute to the development of the embryo
b. Solanad type	2. The basal cell undergoes no further division and the suspensor, if present, is always derived from the terminal cell
c. Asterad type	3. The basal cell plays only a minor role or none in the subsequent development of the embryo
d. Caryophyllad type	4. The basal cell usually forms a suspensor of two or more cells
