D Correct answer
Explanation

Wood charcoal is used to decolorize raw sugar through the process of adsorption where impurities stick to the porous charcoal surface. The activated carbon in wood charcoal has a massive surface area that traps colored compounds. This process filters out the brown color from raw sugar juice, producing the white refined sugar we commonly use.
