Cycas has two cotyledons but not included in angiosperms because of (a) naked ovules (b) seems like monocot (c) circinate ptyxis (d) compound leaves.
Option A Cycas belongs to Order Cycadales of gymnosperms because it has naked seed. It is not enclosed inside a fruit. It does not have double fertilization and so the endosperm formed is haploid in nature and not triploid. So it is not included in angiosperms as they have ovules (or seeds) produced inside fruit. This is the main difference between gymnosperms and angiosperms.
