Choose the correct answer from the options given below:

A.
A-III, B-IV, C-I, D-II
B.
A-II, B-III, C-IV, D-I
C.
A-III, B-I, C-II, D-IV
D.
A-II, B-I, C-III, D-IV

Show answer and solution

Correct option: C

Solution

Chlorophyll contains Mg²⁺ as the central metal ion → A-III. Soda ash is the common name for Na₂CO₃ → B-I. Plaster of Paris (CaSO₄·½H₂O), a form of CaSO₄, is used in dentistry and ornamental work → C-II. Ca(OH)₂ (slaked lime) is used in white washing → D-IV. This gives A-III, B-I, C-II, D-IV, which is option 3.
