A student is drawing an image formed by a thin lens and can clearly construct the $P$-ray and $M$-ray. Which statement is most accurate?

Those two rays are sufficient to locate the image because the image point is where the two rays or their backward extensions intersect.

All three principal rays must always be drawn because any two rays generally intersect at different points.

Two rays are sufficient only for converging lenses, not for diverging lenses.

Only the $F$-ray and $M$-ray may be used to determine image position for a lens.
