the correct option(s) is(are) 

Options:(select one or more)

Answer:
A, B
Solution:

Starting compound (nitrotoluene) on reduction with reagents like Sn/HCl or H₂/Pd (P) forms aniline derivative (Q).

Treatment with NaNO₂/HCl (R) converts it into a diazonium salt (S).

On hydrolysis (H₂O), diazonium salt gives phenol (T). Strong oxidation (U, KMnO₄/KOH, heat) converts the –CH₃ group into –COOH, forming benzoic acid. Hence the correct sequence matches option (A & B).
