Let the volume of mixture $A$ be $200\text{ ml}$, which implies the quantity of cocoa in the mixture is $120\text{ ml}$, and the quantity of sugar $\ln$ the mixture $80\text{ ml}$.Similarly, let the volume of the mixture be $300\text{ ml}$, which implies the quantity of coffee, and sugar in the mixture is 210 , and $90\text{ ml}$, respectively.Now we combine mixture $A$, and $B$ in the ratio of $2: 3$ (if $200\text{ ml}$ mixture $A$, then $300\text{ ml}$ of mixture $B$ ).Hence, the volume of the mixture $C$ is $(200+300)=500\text{ ml}$, and the quantity of the sugar is $(90+80)=170\text{ ml}$.Now he mixes $C$ with an equal amount of milk to make a drink, which implies the quantity of the final mixture is $(500+500)=1000\text{ ml}$The quantity of sugar in the final mixture is $170\text{ ml}$.Hence, the percentage is $17\%$The correct option is A
