Assertion (A): Alkali metals and their salts impart characteristic flame colours. Reason (R): Alkali metals have low ionization enthalpy values. So, electron excitation is possible. The correct option among the following is
- A \((\mathrm{A})\) and \((\mathrm{R})\) are true. \((\mathrm{R})\) is the correct explanation for (A)
- B (A) and (R) are true. (R) is not the correct explanation for (A)
- C (A) is true but (R) is false
