Answer:

A. It passes wthout any deviation

Explanation:

In real lenses the light does not go straight through, there is a refraction. But we can assume that that it passes without any deviation because the center of a lens is comparatively flat that the other points of the lens.

Answer:

A.  It passes without any deviation.

Explanation:

For making ray diagram, following rules are followed:

  1. A ray of light incident parallel to the principal axis converges or appears to diverge from focus.
  2. An incident ray passing through the focus becomes parallel to the principal axis after passing through the lens.
  3. A ray of passing through the center of a lens passes without deviation.

Thus, the correct option is A.
