C Root modification means permanent structural changes in the roots. Modification of the roots is simply the change found in physiology and morphology of the root for a particular adaptation as for storage of food, respiration, mechanical support. The roots are altered to allow a plant to adapt more effectively to the environment in different forms, by performing specific functions other than those of their normal function.

Dahlia has:
1 tendrillar roots
2 respiratory roots
3 nodular roots
4 storage roots
Explanation:
D Dahlia has a storage types of roots. Dahlia and Asparagus are some other examples of plants with modified roots for food storage. Storage roots are the roots that are specially modified for storage of food and water. In Dahlia fasciculated root is present in which roots arise in cluster from lower node of stem and thickened in entire length.

The following is a xerophyte, containing air spaces in the stem and roots:
1 Eichhornia
2 Opuntia
3 Aloe
4 Rhizophora
Explanation:
B Opuntia is a xerophyte, which is containing air spaces in the stem and roots. Its stem is modified into a succulent and flat green structure. Opuntia modified leaves thick cuticle and flat green leaf like structure is known as phylloclade's which performs the functions of photosynthesis. The leaves gets modified into spines to help in reducing transpiration.

Pneumatophores are usually present in
1 Murraya
2 Eichhonia
3 Avicennia
4 None of these
Explanation:
C Pneumatophores are usually present in 'Avicinnea'. Pneumatophores are specialized roots developing in mangrove plants. Avicennia is a mangrove species. It develop a flat root system. Avicennia and Rhizophora are facultative halophytes and have mechanisms to inhibit salt absorption by their roots and to excrete salt from their leaves.
