Why are humans so genetically similar within our species?

A ship was caught in a storm and landed on a small island in the middle of the South Pacific. For generations, no one encountered this small colony who, despite the odds, made a thriving settlement on their island. After many years, what characteristics would be unique about this island population?
a. The people would look very different from each other, and may have evolved some odd characteristics that aren't seen in other humans.
b. The people would look very different from each other, and may exhibit abnormally high occurrences of genetic diseases that are rare in the general human population.
c.The people would look very similar to each other, and may exhibit abnormally high occurrences of genetic diseases that are rare in the general human population.
d. The people would no longer be considered humans after evolving independently for several generations.
