Correct option is D)

In reversed phase chromatography, the stationery phase is hydrophobic in nature.
In the above mentioned options, cyano group, phenyl group and carbon chain all are hydrophobic in nature. Their interaction with water is not at all good. And hence, being hydrophobic, they can be used as a stationery phase in reversed phase chromatography`.
