A
it has haploid endosperm
B
it has dioecious habit
C
it has naked ovules
D
it has two types of leaves, scaly and foliage.
Answer
it has naked ovules
Explanation
Solution
Inspite of Cycas having two cotyledons (unequal unlike angiospermic dicots) is placed with gymnosperms because it has naked ovules not covered inside an ovary. Presence of ovary and a flower is the most distinguishing and characteristic feature of angiosperms. After fertilisation, the ovary develops into fruit which encloses and protects seeds which develop from ovules.
