(a) pass through the pole
(b) be parallel to the principal axis
(c) retrace its path
(d) pass through the centre of curvature​

Answer 1

$\huge{\underline{\sf{Question :-}}}}$

If an incident ray passes through the focus, the reflected ray will

(a) pass through the pole

(b) be parallel to the principal axis

(c) retrace its path

(d) pass through the centre of curvature

$\huge{\underline{\sf{Answer :-}}}}$

If an incident ray passes through the focus, the reflected ray will be parallel to the principal axis.

➜ A ray passing through principal focus of a concave mirror or a ray which is directed towards the principal focus of a convex mirror, becomes parallel to the principal axis after reflection. Hence a real, inverted and enlarged image will be formed.

Therefore, the correct option is option number (b).
