Answer:

(i) is the correct option.

Explanation:

Concave lens gives a diminished image.

Convex lenses give a magnified image of an object when placed between the radius of curvature and the focal length. In addition, magnification is greater for convex lenses with shorter focal lengths. Therefore, to read small letters in her book, Tanya's grandmother should use a convex lens kept at a distance F and 2F from the book.

(i) is the correct option.
