couldnt be 'D' cause yeah while alive organisms do absorb carbon 14 that still defeats the purpose of dating with the carbon 14 method cause its still also taking in carbon dioxide, so the carbon-14 molecules will just keep filling until the organism dies. the whole point of dating with carbon 14 is to measure its deplenish (dying) not continual replenish (living)
