$2-\text{Methylpropanoic acid}$

(C) Step $1$: Isopropyl magnesium chloride is $(CH_3)_2CHMgCl$.Step $2$: Reaction with dry ice $(CO_2)$ forms a complex: $(CH_3)_2CHMgCl + CO_2 \rightarrow (CH_3)_2CHCOOMgCl$.Step $3$: Acidic hydrolysis of the complex yields the carboxylic acid: $(CH_3)_2CHCOOMgCl + H_2O/H^+ \rightarrow (CH_3)_2CHCOOH + Mg(OH)Cl$.Step $4$: The product $(CH_3)_2CHCOOH$ is $2-\text{Methylpropanoic acid}$ (also known as isobutyric acid).
