Sorenson's index can be calculated as:

Sorenson's index = (2 * number of shared species) / (number of species in community 1 + number of species in community 2)

In this case, the number of shared species is 6, the number of species in community 1 is 10, and the number of species in community 2 is 15.

Sorenson's index = (2 * 6) / (10 + 15) = 12 / 25 = 0.48

Therefore, the answer is C, 0.48.
