The number of quadrilaterals that can be made using any 4 points out of total 8 points on the given circle = $$^8C_4$$ = 70
The number of triangle that can be made using any 4 points out of total 8 points on the given circle = $$^8C_3$$ = 56
Thus, the required difference = 70-56 = 14
Hence, option B is the correct answer.
