Which statement correctly defines a binary compound?

Explanation:
Binary compounds consist of exactly two different elements joined together in a fixed ratio. The statement that it contains two different elements aligns with this idea, because a binary compound is defined by having two elements chemically bonded, such as NaCl or H2O. The other descriptions describe mixtures or single-element species: having many elements in random ratios isn’t a single compound of two elements, containing only one element isn’t a compound of two elements, and containing three elements exceeds the two-element requirement.
