(ii) Iodine has same physical state but different colour as compare to other members of the group.
(iii) Fluorine shows no positive oxidation state.
(iv) In $X_2(g)+H_{2}O(l)\to HX(aq)+HOX(aq)$
(where $X_2=Cl$ or $Br)$

• A. (i), (ii) and (iv)
• B. (i), (iii) and (iv)
• C. (ii), (iii) and (iv)
• D. (iii) and (iv)
