Answer:

Correct Answer: 25. (b,d)

Solution:

PLAN: Phenolic compounds in alkaline solution react with chloroform $\left(\mathrm{CHCl}_3\right)$ at a temperature lower than that of $\mathrm{CHCl}_3$ to form ortho-isomer as the major product (due to greater stability resulting from intramolecular hydrogen bonding).

Major as stable due to intramolecular $H$-bonding.

Thus, (b) and (d) are correct.
