Answer:
I believe that its answer "A"
Explanation:
Assertion:
When an object is placed at the focus of a concave mirror, the image formed is real, inverted, and magnified.
This assertion is true for concave mirrors. When an object is placed at the focus of a concave mirror, the reflected light rays are then directed parallel to each other. These rays then converge at a single point, forming a real, inverted, and magnified image.
Reason:
The image formed by a concave mirror is always real and inverted, but the magnification depends on the distance of the object from the mirror.
This reason is also accurate. The image formed by a concave mirror is indeed always real and inverted. The magnification, however, is directly related to the distance of the object from the mirror. When the object is at the focus of a concave mirror, the image is highly magnified.
Therefore, both the assertion and reason are accurate. The image formed by a concave mirror is indeed real, inverted, and magnified when the object is placed at the focus. Additionally, while the image is always real and inverted, the magnification does depend on the object's distance from the mirror.
