The following graph does not represent a decay curve. Explain.

Based on the graph, the half-life of the sample is six hours, but the second half-life is approximately 15.0 hours. The second half-life should be 12.0 hours.

After six half-lives, a decay curve should be approaching zero. The graph indicates that out of the 100 g sample, 17.0 g (17.0%) remain after six half-lives.

Both A and B

None of the above
