State True and False:

If object lies at infinity, then image location will be at $F$ for a concave mirror.

• A. True
• B. False

The correct option is A True

If the object is placed at infinity, then all the rays appear to come parallel to the principal axis. And all these rays pass through the focus of the concave mirror after reflection, thus image is formed at the focus.
