Solution
The correct option is C 3-Pentanone
Electrophilicity of carbonyl carbon is decreased by electron donating group present on it. Nucleophile attacks on the crabonyl carbon bearing more positive charge. In 3-pentanone, ethyl groups decrease the partial positive charge on crbonyl carbon and rate is diminished.
