The correct option is D ii, iv
Cladodes
are modified stems with limited growth. They are photosynthetic
shoots. Branches of cladodes in Asparagus perform
photosynthesis. Tendrils are modified leaf which helps in climbing.
In Australian acacia, the petiole is modified into phyllode. It helps
in photosynthesis. In Agave, floral buds store food materials.
In Diascorea, vegetative buds store food material.
Taeniophyllum contains aerial roots which act as assimilatory
root. They contain green pigment and are involved in photosynthesis.
However, they are not reproductive root and hence does not help in
vegetative propagation. Thus,
the correct answer is 'ii, iv.'
