D. Inferior oblique and Inferior rectus

The correct answer is : A. Superior rectus and inferior oblique

Action of Individual Muscles:

Levator Palpebrae superioris - Elevation of upper eyelid

Superior rectus - Upward rotation, medial rotation and intorsion

Inferior rectus- Downward rotation, medial rotation and extorsion

Medial rectus- Medial rotation

Lateral rectus- Lateral rotation

Superior oblique- Downward rotation, lateral rotation and intorsion 

Inferior oblique- Upward rotation and extorsion

Upward rotation (Elevation)- Superior rectus and inferior oblique

Downward rotation (Depression)- Inferior rectus and Superior oblique

Medial rotation (Adduction)- Medial rectus, Superior rectus and Inferior rectus

Lateral rotation (Abduction)- Lateral rectus, Superior oblique and inferior oblique

Intorsion- Superior rectus and superior oblique

Extorsion- Inferior oblique and Inferior rectus
