hello i just need the correct answer choice. Thank you. No work is needed

1. (3 points each) For all parts of this question, circle the correct answer. (In each part there is only one correct answer and there is no partial credit.) a. The derivative of f (x) = 3Vx2 - 27 + In (5x) is (i) -x1/2 + 2.7x-2+ - 6 1 (1) 3 x1/3 + 2.7x-2 + - (111) 2x-1/3 + 2.71nx + - - x1/2 + 2.7x-2 + - 5x none of the above b. The derivative of f (t) = 532 12 t+ evt+3 + nt (i) 532 (12 t+ eVi+3 z + "] (12 + 0.5evc+3 (t + 3) -0.5) (1i) -532(12+0.5eVt+3 (t+3)-0.5) - + T (12 t+ evt+3)2 -532 (iii) + TC 12+0.5evt+3(t+3)-0.5) (iv ) none of the above c.
