Solution

The correct options are
A It is always inverted.
B It can be obtained on the screen.
C The light rays after refraction intersects at one point.
When light rays converge after refracting and intersects at a point, a real image is formed. It can be obtained on a screen. A real image is always inverted (for a normal object).
