\nThe correct option is B. Melting of ice is a physical change because water changes its state from solid (ice) to liquid (water), but its chemical composition (H\u2082O) remains the same. Burning of a candle is a chemical change because the wax (a complex hydrocarbon) reacts with oxygen in the air to produce new substances like carbon dioxide, water vapor, soot, heat, and light.

\nThe question differentiates between physical changes (alteration in form, not composition) and chemical changes (formation of new substances).

\nOther examples of physical changes include boiling, freezing, condensation, sublimation, breaking glass, and dissolving salt in water (where the salt can be recovered). Examples of chemical changes include rusting of iron, cooking food, digestion, photosynthesis, and explosion of fireworks.
