The element used for radioactive carbon dating for more than

\mathrm{56000 }\,\mathrm{yr}

View answer and explanation

Correct option: A

\mathrm{C - 14}

Option A (C - 14) is correct because Carbon-14 dating is used for dating organic materials up to around 50,000 years, making it suitable for dating beyond 56,000 years, while other options are used for much longer timescales.
