Potassium is most likely to be found with 6.25% of its original amount in 6 billion years because the half life of Potassium-40 is 1-1.5 billion years in graph. Thus the correct option is C.

If it half in 1 to1.5 billion years = 50% gain

1-1.5 billion years = 25%. gain

If we do that 2 more times we will get 12.5% and then 6.25% gain.

<h3>What is half life?</h3>

Half life is defined as the time required for half of the atoms of a radioactive substance to become disintegrated.

Our estimate is about 1-1.5 billion years so repeating that about 4 times we get around 4-6 billion years for it to gain 6.25%.  From this it can be concluded that Potassium-40 as since it comes the closest to remaining at 6.25% its original amount after approximately 6 billion years.
