Answer options

  1. was sitting
  2. was seated
  3. had been sitting
  4. am sitting

Correct answer and explanation

Correct answer: was sitting

Explanation: The sentence describes an action in progress in the past (sitting in the library) that was interrupted by another action (someone threw a ball). In English grammar, this structure requires the Past Continuous tense. A. was sitting ✅ – correct; shows an action happening at that time. B. was seated ❌ – passive form; unnatural here. C. had been sitting ❌ – past perfect continuous; implies a longer duration before another past action, not needed here. D. am sitting ❌ – present tense; does not fit with the past context. Correct Sentence: While I was sitting in the library, someone threw a ball through the window. ✅
