Answer:
first one is correct
: It is always formed behind the mirror, between the pole and its focus.
Explanation:
The image formed in a convex mirror is always virtual and erect, whatever be the position of the object. ... When an object is placed at infinity, a virtual image is formed at the focus. The size of the image is much smaller as compared to that of the object.
