Answer 1

The correct option is C

element, compound

An element is a simple substance which cannot be further divided into one or more pure components by any chemical means. Whereas a compound is a chemical combination of two or more elements. For example, water consists of hydrogen and oxygen. Hydrogen and oxygen are elements and cannot be further broken down. But water can be broken down to obtain hydrogen and oxygen. Hence, water is a compound which consists of elements hydrogen and oxygen.
