First, we restate the question and options to set the stage for analysis.
Question: When the image of an object is seen in a concave mirror the image will:
Options:
 a. will always be magnified.
 b. always be virtual.
 c. be either real or virtual.
 d. always be real.

Now, evaluate each choice:
Option a: 'will always be magnified.' This is incorrect because a concave mirror can produce magnified images when the object is placed between the focal point and the mirror, but it can also produce diminished or even no magnification when the object is at other positions (e.g., beyond the center of curvature), and in some cases the image is not magnified at all. Therefore, the statement is not universally true.

Option b: 'always be virtual.' A concave mirror does produce virtual images when the object is located between the focal point and the mirror, but when the object lies beyond the focal point, the image is real and can be projected on a screen. Hence, the image is not always virtual.

Option c: 'be either real or virtual.' This statement captures the full range of possibilities for concave mirrors: depending on the object's distance from the mirror relative to the focal length, the image can be real (outside the focal point) or virtual (inside the focal point). This aligns with the fundamental mirror equation and ray behavior.

Option d: 'always be real.' As explained for option b, there are conditions under which the image is virtual (for example, when the object is between the focal point and the mirror). Therefore, this claim is incorrect.

In summary, the correct understanding is that a concave mirror can form either a real or a virtual image depending on the object distance relative to the focal length, which matches option c.
