Correct answer: B. The Tyndall effect is the scattering of light by colloidal particles. It is observed in colloidal solutions and suspensions, but not in true solutions.
(A) Mixture of water and milk: Milk is a colloid (emulsion), so it shows the Tyndall effect. (True)
(B) Sunlight passing through a canopy of dense forest: The air in a dense forest contains mist, which is a colloid (aerosol of liquid in gas), so it shows the Tyndall effect. (True)
(C) Solution of copper sulphate: Copper sulphate solution is a true solution, so it does not show the Tyndall effect. (False)
(D) Light entering a smoke-filled room through a small hole: Smoke is a colloid (aerosol of solid in gas), so it shows the Tyndall effect. (True)

Therefore, (A), (B), and (D) will show the Tyndall effect.
