This figure shows that the image of a candle inside the focal point of a concave mirror is virtual, erect, and magnified. Where would the candle's image be if it were placed exactly at the center of curvature, point C?
a. A real inverted image is formed at an infinite distance to the left and infinite in size. b. A virtual erect image is formed at an infinite distance to the right and infinite in size. c. The inverted image is formed with the same size as the object, also located at the focal point, but on the opposite size of the optical axis.
