Which of the following acids is not capable of undergoing HVZ reaction ?

Write HVZ reaction.

Carboxylic acids having at least one alpha -hydrogen react with Cl_(2)" or "Br_(2) in the presnence of red phosphorus to give alpha -halo acids. The reaction is known as H.V.Z. reaction. The HVZ reaction is limited to the formation of alpha -chloro acid and alpha -bromo acid and it is sometimes difficult to carry out the reaction. Answer the following questions : Which of the following carboxylic acids will not give HVZ reaction ?
