The formula for calculating the degrees of freedom for error in a two-way ANOVA is (n-1) * (b-1) * (g-1), where n is the number of observations per cell, b is the number of blocks, and g is the number of groups. Substituting the given values, we get (2-1) * (3-1) * (5-1) = 15. Therefore, the correct answer is B.
