We have four points L, T, V, X on the plane Z.
According to defination of plane, any three of the four points will define a plane.
Let us discuss the given option:
A. Plane V : V is just a point not a plane.
B. Plane LTX : LTX form a straight line not a plane.
C. Plane TLV : All those three point T, L, V are in same plane Z. Therefore, another name for plane XLV is TLV.
D. Plane ZXV : Z is not a point on the plane. Z is itself a plane.
Therefore, correct option is C. Plane TLV.
