The correct option is D Monocotyledon - Mustard : Dicotyledon - Lilies
Angiosperms are divided into two classes - the dicotyledons and the monocotyledons. The dicotyledons are characterised by seeds having two cotyledons and reticulate venations in
leaves, Eg. Rose, Eucalyptus, cotton, mustard, etc.
The monocotyledons on the other hand are characterised by single cotyledons and parallel venation in leaves. Eg. banana, palm, orchids, lilies etc.
