Write the correct preposition in the blank space from the given options:
"Hari is inferior ________ Ram in intelligence."

The correct answer is Option B (to).

Key Points:
• Latin Comparative Adjectives (inferior, superior, senior, junior, prior, anterior, posterior) take the preposition 'to', never the conjunction 'than'.
• Words of Latin origin ending in '-ior' are followed by 'to' to denote comparison.
• Therefore, 'Hari is inferior to Ram in intelligence' is the only grammatically correct structure.
• 'Than' is commonly and erroneously chosen by learners under the influence of regular English comparative adjectives (e.g., taller than), but is strictly incorrect after Latin comparatives.
• Key Takeaway: Latin comparative adjectives ending in '-ior' (inferior, superior, senior) always take 'to'.
