The rest of the question is the attached figure

According to the graph, we will check which option is true.

a. Line h intersects line f at two points, A and B (Wrong)

Because: h intersects line f at B only.

b. Line h is the intersection of planes R and T (Wrong)

Because: g is the intersection of planes R and T

c. Line h intersects plane P at point C (Wrong)

Because: h intersects plane P at point B

d. Line h has points on planes R, P, and T (True)

Because h has the point B on the plane P, h has the point A on the plane T

and the points of h on the plane R
