Let F= (x,y) and C be the circle of radius 3 centered at the origin oriented counterclockwise. Evaluate O F F-dr by parameterizing C. !! Choose the correct answer below and, if necessary, fill in the answer box to complete your choice. ag and dy af results in a nonzero value of O A. For F= (f.g) and r(t) = (x(t),y(t). evaluating the integral using dap results in a nonzero value of O B. For F= Vq and r(t) = (x(t),y(t}, evaluating the integral using and dy dy and dt dx results in a nonzero value of %3D O C. For F= (f.g) and r(t) = (x(t).y(t)), evaluating the integral using dt ag and af results in a nonzero value of %3D O D. For F= (f_g) and r(t) = (x(t).y(t)), evaluating the integral using %3D !! dy O E. The value of the integral is 0.
