  • A
    Solution of Animal charcoal Sorption sugar
  • B
    $\begin{array}{lll}\text { Animal } & \text { Solution of } & \text { Absorption } \\ \text { charcoal } & \text { sugar } & \end{array}$
  • Correct answer
    C
    $\begin{array}{lll}\text { Animal } & \begin{array}{l}\text { Colouring } \\ \text { charcoal }\end{array} & \text { substance }\end{array}$
  • D
    colouring Animal charcoal Adsorption substance
