Consider the following region R and the vector field F. a. Compute the two-dimensional divergence of the vector field. b. Evaluate both integrals in the flux form of Green's Theorem and check for consistency. F = (x,y); R= (xy): x+y- =9 a. The two-dimensional divergence is . (Type an exact answer.) Evaluate these integrals and check for consistency. Select the correct choice below and fill in the answer box(es) to complete your choice. (Type an exact answer.) O A. The integrals are consistent because they both evaluate to O B. The integrals are not consistent. The double integral evaluates to but evaluating the line integrals and adding the results yields
