So I tried googling some of the text of his post, and found that a lot of it is copy-pasted, verbatim from pages like this: which again, makes claims without any sources to check. most organisms contain more potassium than carbon d. it is found only in certain rock layers The answer you are looking for is A. I notice that @a_measured_brush makes a LOT of claims without a *single source*.
The rate of decay - the rate at which the clock ticks - is measured as the half-life, which is the time it takes for the quantity of isotope to be halved.

As soon as a living organism dies, it stops taking in new carbon.
What scavengers like vultures and hyenas leave behind, flies, ants, worms, and bacteria quickly consume.
Within three weeks, there will be nothing left but a few small bones." A fossil normally preserves only a portion of an organism, usually that portion that was partially mineralized during life, such as bones and teeth.
