Answer to Question 1

E

Answer to Question 2

The angular mag. is the ratio of ANGULAR size looking through the instrument compared to the angular size without. The lateral magnification is the ratio of the actual size of image compared to that of the object. The two magnifications are comparing different things. As an example: the moon may appear larger (in angle) through a telescope but the image is certainly smaller than the moon itself.
