Explanation:

Root type Description
 Carrot
  • In carrots, roots are modified for storing reserve food materials.
  • These modified roots usually are swollen and assume different forms.
 Stilt root
  •  Stilt roots are adventitious aerial roots.
  • They grow obliquely downward from the main stem's basal nodes and attach firmly to the soil. 
  • they provide anchorage to plants and do not provide much support.
 Pneumatophores
  • A specialised root that rises out of the water or mud upwards to enter the air.
  • They gain oxygen for the root systems of trees living in swampy or tidal environments.
  • Example: Mangrove
 Prop roots
  • Banyan trees are characterized by aerial roots, that hang from the branches.
  • These roots mature into thick, woody trunks, called prop roots.
  • Prop roots can become indistinguishable from the primary trunk with age.
  • They provide support to the main trunk to bear the load of the tree.

Thus, the correct match is (a) - (iii), (b) - (i), (c) -(iv), (d) - (ii)
