Given a function , how does the gradient of q produce a vector field? Choose the correct answer below. A. The gradient of q, which is Vo = (@(x,0,0).p(0,y,0),(0,0,z)), assigns to each point in a region D of R" a vector field (f(x.y,z).g(x.y,z),h(x,y.z) . O B. The gradient of p, which is Vo= (@ @1 02), assigns to each point in a region D of R" a vector field (f(x,y,z).g(x,y,z),h(x.y.z)) . O C. The gradient of , which is Vo= (@x,
