Given: Equation of parabola is 3x2=8y The given equation can be re-written as: x2=4.(2∕3)y .........(1) Now by comparing the equation (1), with x2=4 ay we get ⇒ a = 2/3 As we know that, focus of the parabola of the form x2=4 ay is given by: (0,a) So, the focus of the given parabola is (0, 2/3) Hence, option B is the correct answer.
