Solution

The correct option is D
Among the given options, Br group is ortho/para directing whereas other groups are meta-directing in nature. Here Br donates its lone pair which increases electron density at ortho/para positions in the ring. In the electrophilic attack, more the electron density, faster is the reaction. So, (d) is correct.
