Answer 1

Answer: (A), (C), (D)

The correct options are
A They have parallel venation.
C Seeds of these plants have a single cotyledon.
D They have fibrous root system.

The seeds of monocotyledonous plants have a single cotyledon. Other physical characteristics of monocotyledonous plants include:
1) Parallel-veined leaves
2) Fibrous root system
3) The parts of the flower, i.e., the number of petals and sepals are in sets of 3 or its multiples, but never 5.
Other characteristic features include scattered vascular bundles and the absence of cambium in roots and stem.
