Choose the correct answer from the options given below :

  1. A A-II, B-IV, C-I, D-III
  2. B A-II, B-III, C-I, D-IV Correct answer
  3. C A-III, B-IV, C-II, D-I
  4. D A-II, B-III, C-IV, D-I

Solution

<p>In this problem, we are matching chemical compounds with their corresponding color. Let&#39;s go over each one :</p> <p>A. $Mg(NH_4)PO_4$ - Magnesium ammonium phosphate is white in color, so A matches with II.</p> <p>B. $K_3[Co(NO_2)_6]$ - Potassium hexanitritocobaltate(III) is a yellow complex, so B matches with III.</p> <p>C. $MnO(OH)_2$ - Manganese hydroxide is brown in color, so C matches with I.</p> <p>D. $Fe_4[Fe(CN)_6]_3$ - Prussian blue or Ferric ferrocyanide is deep blue in color, so D matches with IV.</p> <p>So, the correct option is Option B: A-II, B-III, C-I, D-IV.</p>
