Solution:

Only statement II is correct about moniliform roots, that these are swollen roots at regular intervals imparting bead-like appearance of necklace, e.g. Momordica.
Rest all statements are incorrect and can be corrected as
- Fasciculated fleshy roots are modified adventitious roots, in which swollen roots or root tubers occur in clusters from lower nodes of stem, e.g. Dahlia and Asparagus. In Curcuma, nodulose roots are found, where the swellings occur only near the tips.
- Aerial or Epiphytic roots hang down in air, they do not possess root caps and root hairs instead they possess a covering of dead spongy tissue called velamen.
