Which of the following reactions of bromobenzene are correct?

Bromobenzene inserts magnesium in dry ether (aryl Grignard) and undergoes Wurtz-Fittig coupling with an alkyl halide and sodium to give toluene. Because the C-Br bond is strong, it is not hydrolysed by aqueous alkali at room temperature (Dow process needs 623 K and 300 atm) and it gives no $\mathrm{AgBr}$ with aqueous $\mathrm{AgNO}{}_3$.
