Correct Answer: B
Solution :
Hydroxide of group 2 element, KOH and lime water i.e., \[Ca{{(OH)}_{2}}\] are basic in nature which turn China rose indicator green. Oxide of element belonging to group 16 and period 3 i.e., \[S{{O}_{2}}\] and oxide of element having electronic configuration 2, 4 i.e., \[C{{O}_{2}}\] are acidic in nature which turn China rose indicator magenta.
