Answer :
The angle of the orbital angular momentum is option (B) 66 degrees.
The formula for finding the angle between the z-axis and the angular momentum is given by cosθ = m/√(l(l+1)), where m is the magnetic quantum number, l is the angular momentum quantum number, and θ is the angle between the z-axis and the angular momentum.
Plugging in the given values, we have: m = -1l = 2θ = cos^(-1)(-1/√[2(2+1)])= cos^(-1)(-1/√6)≈66 degrees.
Therefore, the answer to the given student question is option (B) 66 degrees.
