The stars at the turnoff point in the H-R diagram of the Hyades star cluster have an absolute magnitude of approximately m= + 2, whereas those at the turnoff point in the cluster M41 have M= 0. From this information, we can say with certainty that
A) the Hyades cluster has more stars in it than M41
B) the Hyades cluster is younger than M41
C) the Hyades cluster is older than M41
D) the Hyades cluster is farther away than M41
