Question Explanation: Question is asking about match the column.

Concept: This question is based on element , compound and mixture.

Solution :

Element : It is a pure substance which consists of atom of same kind.

Compound : A chemical substance containing atoms from more than one element held together by chemical bonds.

Mixture : A material made upto two or more substances which can be separated by physical method.

(A) Elements are pure substances. Hence, they cannot be broken down further. $A \to P, R, S, T$

(B) Compound can be through chemical reaction. $B \to P, Q, S, U$

(C) Mixture can be decomposed via physical as well as chemical methods. It is heterogenous. $C \to Q, U$

(D) $H_{2} O$ is a compound. $D \to P, Q, S, U$

(E) $Fe (s) + S (s)$ in powered form is a mixture. However the individual elements can not be decomposed further. $E \to Q$ , U
