Correct option is A
The correct answer is (a).
The zygote is not unpolarized with respect to its intracellular composition. In Arabidopsis, the zygote undergoes polarization prior to the first mitotic division. The apical-basal axis of the zygote is established through the distribution of cellular components, which influences its developmental fate. The other statements are correct with respect to Arabidopsis embryogenesis and pattern formation.
Incorrect options-
Option (b) is correct: The two daughter cells from the first zygotic division have distinct fates; this is essential for proper embryo patterning.
Option (c) is correct: Basal quartet cells contribute to root meristem apical regions.
Option (d) is correct: Hypophysis forms the quiescent center of root apical meristem.
