Correct option is (c) higher, harder

Easy explanation: The points of difference are that the beryllium is denser and harder than other members of its family and it has a higher melting point that is 1551 Kelvin while that of magnesium is just 924 Kelvin. So we can say that beryllium has a higher melting point and is harder than other members of its family.
