Correct Answer & Explanation
Option A
• The word 'never' combined with 'before' indicates an experience up to the present moment.
• This context requires the Present Perfect Tense, which talks about actions completed at an unspecified time in the past but relevant to the present, or experiences up to now.
• The structure for Present Perfect Tense is Subject + have/has + V3 (Past Participle) + Object.
• 'I' takes 'have', and the past participle of 'see' is 'seen'.
