a and b Explanation: A magnifying glass is a single convex lens of lesser focal length. When a magnifying glass is used, the object to be viewed can be brought closer to the eye than the normal near point. This results in a larger angle being subtended by the object at the eye and hence, viewed in greater detail. Moreover, the formation of a virtual erect and enlarged image takes place.
