Which of the following give a ketone as the main product after work-up?

1. A$\mathrm{C}{}_6\mathrm{H}{}_5\mathrm{CN}$ with $\mathrm{CH}{}_3\mathrm{MgBr}$, then $\mathrm{H}{}_3\mathrm{O}{}^{+}$
2. Bbenzene with $\mathrm{CH}{}_3\mathrm{COCl}$ and anhydrous $\mathrm{AlCl}{}_3$
3. C$\mathrm{CH}{}_3\mathrm{CH}{}_2\mathrm{COCl}$ with $(\mathrm{CH}{}_3){}_2\mathrm{CuLi}$
4. D$\mathrm{C}{}_6\mathrm{H}{}_5\mathrm{COCl}$ with excess $\mathrm{CH}{}_3\mathrm{MgBr}$, then $\mathrm{H}{}_3\mathrm{O}{}^{+}$
