Answer: (A)

Verified step by step guidance

1. Step 1: Understand the root terms related to eye positioning. The suffix '-tropia' refers to a turning or deviation of the eye.
2. Step 2: Break down the prefixes: 'Exo-' means outward, 'Eso-' means inward, 'Peri-' means around, 'Meso-' means middle, and 'Hypo-' means below or downward.
3. Step 3: Match the prefix with the direction of eye turning. Since the question asks for outward turning, focus on the prefix 'Exo-'.
4. Step 4: Combine the prefix and suffix to form the term describing outward eye turning: 'Exotropia'.
5. Step 5: Confirm that 'Exotropia' is the correct term for outward turning of the eyes, distinguishing it from 'Esotropia' (inward turning) and 'Hypotropia' (downward turning).
