Yellow coloured aquesous solution of sodium chromate changes to orange when acidified with sulphuric acid because

A

`H^(+)` ions convert chromate ions to dichromate ions

B

`H^(+)` ions react with sodium chromate to give sodium ions which turn solution orange

C

`Cr^(3+)` ions are liberated in the solution which turn the solution orange

D

sodium hydroxide is formed during the reaction which imparts orange colour to the solution.
