Solution

The correct option is C $C r_{2} (S O_{4})_{3}$
When $K_{2} C r_{2} O_{7}, C a C l_{2}$ , and conc. $H_{2} S O_{4}$ are heated, $C r_{2} (S O_{4})_{3}$ is formed.
$K_{2} C r_{2} O_{7} + 3 C a C l_{2} + 7 H_{2} S O_{4} \to C r_{2} (S O_{4})_{3} + K_{2} (S O_{4}) + 3 C a (S O_{4}) + 3 C l_{2} + 7 H_{2} O$ .
