Abnormal/anomalous secondary growth occurs in
1 Dracaena
2 ginger
3 wheat
4 sunflower
Explanation:
Exp:A Monocot trees such as palms grow in thickness by primary thickening meristem situated at the base of the leaf plants like Dracaena show secondary growth by a special cambium. It develops in the form of strips just outside the vascular region. This cambium strips produce secondary vascular bundles which is amphivasal in dracaena.

Examples for lateral meristems are
1 Fascicular cambium and procambium
2 Procambium and dermatogen
3 Fascicular cambium and cork cambium
4 Phellogen and procambium
Explanation:
Exp:C Lateral meristems are also called secondary meristems. The vascular cambium produces secondary xylem and phloem. Cork and fascicular cambium help in secondary growth.

Casparian thickenings are found in the cells of
1 Pericycle of the root
2 Endodermis of the root
3 Pericycle of the stem
4 Endodermis of the stem
Explanation:
Exp:B Casparian thickenings are found in the cells of Endodermis of the root. Endodermis are the innermost layer of cortex, and casparian strips are made up of suberin act as water-impermeable layer. Casparian strips act as a barrier for harmful chemicals, herbicides etc.

Periderm includes:
1 Cork cambium only
2 Cork cambium and cork
3 Cork and secondary cortex
4 Cork cambium, cork and secondary cortex
Explanation:
Exp:D The Periderm is the secondary shielding (dermal) tissue that replaces the dermis for the duration of an increase in the thickness of the stems and roots of gymnosperms and dicotyledons. In contrast to the everyday dermis, the periderm is a multilayered tissue machine, maximum of which commonly constitutes the cork, or phylum, the cork cambium or phylogeny, and the phelloderm or secondary cortex. The cork cambium, cork and secondary cortex are together referred to as periderm.
