The adjective, 'oval' means 'having the shape like that of an egg'. It is used to describe the shape of a face as well as eyes. Hence, options A and B are correct.
Some adjectives which can be used with 'lips' are: 'full', 'attractive', 'luscious, 'plump', 'rosy', and 'puckered up'. Some adjectives which can be used with 'teeth' are: 'sharp, 'decayed', 'beautiful', 'crooked', 'protruding' and 'pearly'. However, the word, 'oval' cannot be used to describe 'lips' and 'teeth' because these parts of the body cannot be in oval shape.
