Correct option (a) Assertion and Reasoning both are correct, and Reasoning is the correct explanation of Assertion.

The assertion is correct as an element is a pure substance, which cannot be broken down into simpler substances by chemical means, and it consists of only one type of atom. The reasoning is also correct as it explains the reason why the assertion is true. Every element is composed of atoms that have the same number of protons in their nucleus, which makes them identical and gives them unique properties. Therefore, an element is pure because it is composed of only one type of atom.
