List - IList - II
a. Coral reefi. Organic Ocean Deposit
b. Shoalii. Deep flat surface

d. Continental slopeiv. Detached elevation with shallow depth

Codes : a b c d

  • A.ii iii i iv
  • B.iv i iii ii
  • C.iii ii iv i
  • D.i iv ii iii

Answer: D

A coral reef is an organic ocean deposit built by coral polyps (i). A shoal is a detached elevation of the sea floor with shallow depth (iv). An abyssal plain is the deep flat surface of the ocean floor (ii). The continental slope is the steep descent from the shelf bed (iii). The right matching is a-i, b-iv, c-ii, d-iii, which is code D. The other codes confuse the flat abyssal plain with the steep slope or the shoal with the deposit.
