multiple choice
c₁₆h₁₈n₃cls
na₂hpo₃(h₂o)₅
ch₄
c₃h₇o₂n

Explanation:

Organic compounds contain carbon - hydrogen bonds (except for some simple carbon - containing compounds like carbonates, cyanides etc.). $C_{16}H_{18}N_3ClS$, $CH_4$, and $C_3H_7O_2N$ all have carbon - hydrogen bonds. $Na_2HPO_3(H_2O)_5$ is an inorganic compound as it does not have carbon - hydrogen bonds and is a salt - hydrate.

Answer:

B. $Na_2HPO_3(H_2O)_5$
