Which of the following gives the chromyl chloride test?

The chromyl chloride test is used to detect chloride ions in the qualitative analysis. If any chloride salt like sodium chloride is heated with acidified potassium dichromate it produces red color fumes of chromyl chloride. It confirms the presence of chloride ions in that salt.

${\mathrm{PhN}}_2\mathrm{Cl}$ are significantly covalent to produce sufficient ${\mathrm{Cl}}^{-}$ to give this test.
