(B) Bend away from the normal
Glass is a denser medium and air is a rarer medium. A light ray travelling from a denser medium to a rarer medium bends away from the normal.
The key rule to remember: denser → rarer = bends away from normal; rarer → denser = bends towards normal. Glass has a higher refractive index than air, making it the denser medium. The source passage explicitly states: "A light ray travelling obliquely from a denser medium to a rarer medium bends away from the normal." This is the direct fact the examiner tests here.
