Directions: Complete the conversation by choosing the correct option and fill blank (ii).

Abhinava: Nanu, (i)___________ so worried? Nanu: I (ii)____________ for my English paper. I (iii)___________ only general articles. Abhinava: Don’t worry. You (iv)_________ from newspapers or magazines to enhance your reading skill.

Nanu: I feel relieved at your assurance. Thank you for your encouraging words.

The present perfect tense "have not prepared well" is correct because Nanu is explaining his current worry about a past action (or lack thereof) that has present relevance. The conversation shows he's worried NOW about his English paper, and the present perfect connects the past (not preparing) to the present (being worried). The other options are incorrect: "cannot prepare well" is present tense referring to ability, "do not prepare well" is simple present habit, and "would not prepare well" is conditional/hypothetical.
