Find the gradient field of the function.f(x, y, z) = z sin (x + y + z)
A. ?f = -cos xi - cos yj + (sin z - z cos z)k
B. ?f = z cos(x + y + z)i + z cos(x + y +z)j + (sin(x + y + z) + zcos(x + y + z))k
C. ?f = -z cos(x + y + z)i - z cos(x + y +z)j + (sin(x + y + z) - zcos(x + y + z))k
D. ?f = cos xi + cos yj + (sin z + z cos z)k
