Q
S
P
R
Explanation
Addition of $\mathrm{H}-\mathrm{Br}_{(\mathrm{aq})}$ to alkene follows electrophilic addition mechanism. In the rate determining step a carbocation intermediate is formed. Among P, Q, R & S compound Q will form most stable carbocation intermediate since it is resonance stabilized.
