Solution

The correct option is B the mirror and the screen
For an object at infinity, all the paraxial rays after reflection from the concave mirror will pass through the focus, thus the image is formed at focus. Hence the focal length of the concave mirror can be determined by measuring the distance between the screen and the mirror.
