Step 1: Identify the subject and tense clue. Subject: 'The principal' (active, performing the action). Tense clue: 'last year' → simple past tense required. Step 2: Rule out passive options. 'Was presented' and 'had been presented' are passive — they would require 'Priya' as the subject. The subject here is 'The principal', so active voice is correct. Step 3: Rule out present tense. 'Presents' is present tense; 'last year' demands past tense. Answer: 'presented' (simple past active).
