What is the correct free body diagram of the broom?

A
Image with description A free body diagram with 4 force vectors. The first vector is pointing downward, labeled F Subscript g Baseline. The second is pointing right, labeled F Subscript p Baseline. The third vector is pointing upward, labeled F Subscript N Baseline. The fourth vector is pointing left, labeled F Subscript f. The upward vector is the same length as the downward vector. The right vector is the same length as the left vector.
B
Image with description A free body diagram with 3 force vectors. The first vector is pointing downward, labeled F Subscript g Baseline. The second vector is pointing right, labeled F Subscript p Baseline. The third vector is pointing upward, labeled F Subscript N Baseline. All three vectors are of equal length.
C
Image with description A free body diagram with 4 force vectors. The first vector is pointing downward, labeled F Subscript g Baseline. The second vector is pointing left, labeled F Subscript f Baseline. The third vector is pointing upward, labeled F Subscript N Baseline. The fourth vector is pointing down to the right, labeled F Subscript P Baseline. All vectors are the same length.
D
Image with description A free body diagram with 4 force vectors. The first vector is pointing downward, labeled F Subscript g Baseline. The second vector is pointing right, labeled F Subscript f Baseline. The third vector is pointing upward, labeled F Subscript N Baseline. The fourth vector is pointing up to the left, labeled F Subscript P Baseline.
