If a Population Is Quite Small, Does That Justify Making

If a population is quite small, does that justify making a statistical generalization from a very small sample ?

A) No.If the population size is quite small, we should attempt a complete survey of it.
B) No.If the entire population is quite small, nothing significant can be said about it.
C) Yes, because we would still be sampling a large percentage of the whole population (4 out of 25 is 16%!) .
D) Yes, because if the population is very small, its members are likely to be very similar, so even a very small sample will be representative of the whole population.
E) Yes, because generalizations about smaller populations require less evidence.
