Match List - I with List - II.

	List-I		List-II
A	Lyophilic colloid	I	Liquid-liquid colloid
B	Emulsion	II	Protective colloid
C	Positively charged colloid	III	${\mathrm{FeCl}}_3+\mathrm{NaOH}$
D	Negatively charged colloid	IV	${\mathrm{FeCl}}_3+$ hot water

Choose the correct answer from the options given below

• Correct answer
  A

  $\left(\mathrm{A}\right)-\left(\mathrm{II}\right),\left(\mathrm{B}\right)-\left(\mathrm{I}\right),\left(\mathrm{C}\right)-\left(\mathrm{IV}\right),\left(\mathrm{D}\right)-\left(\mathrm{III}\right)$
• B

  $\left(\mathrm{A}\right)-\left(\mathrm{III}\right),\left(\mathrm{B}\right)-\left(\mathrm{I}\right),\left(\mathrm{C}\right)-\left(\mathrm{IV}\right),\left(\mathrm{D}\right)-\left(\mathrm{II}\right)$
• C

  $\left(\mathrm{A}\right)-\left(\mathrm{II}\right),\left(\mathrm{B}\right)-\left(\mathrm{I}\right),\left(\mathrm{C}\right)-\left(\mathrm{III}\right),\left(\mathrm{D}\right)-\left(\mathrm{IV}\right)$
• D

  $\left(\mathrm{A}\right)-\left(\mathrm{III}\right),\left(\mathrm{B}\right)-\left(\mathrm{II}\right),\left(\mathrm{C}\right)-\left(\mathrm{I}\right),\left(\mathrm{D}\right)-\left(\mathrm{IV}\right)$

Hence, the correct answer is option: 'A'.
