Q1. Which pair correctly matches the suffix with the form it builds?
Explanation
The pair kta — kṛta is the correctly matched one. The kṛt suffix kta forms the passive past participle, so kṛ + kta = kṛta, 'done'. The other pairs deliberately cross-wire suffixes with the wrong outputs: tumun makes the infinitive paṭhitum (not paṭhita), śatṛ makes a present participle while kartavya actually needs tavyat, and matup is a taddhita possessive while the agent noun kartṛ needs tṛc. Knowing which suffix yields which category defeats this match trap.
