Find the gradient field F of the function f.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 = cos xi + cos yj + (sin z + z cos z)k D. F = z cos(x + y + z)i + z cos(x + y +z)j + (sin(x + y + z) + zcos(x + y + z))k
