Answer: B. detect an element
Both two answers are wrong. The correct answer is to B. detect an element. For example, a rock type can be detected through carbon dating (half-life), age of recent organic remains of archaeological excavations are also determined through same process

The first question that was repeated the answer was taken to be A which is to create an element and this one the answer is c (which is the correct answer?)

The correct answer is A, assuming the half life of an element is 1000, if the element start to decay to 250 atoms . It means that the Half life of another atom has been created, not the original element.
