Solution

In total, Abeer took part in 8 transactions.

1. Gave 3 and received 2 novels. Thus, Abeer had 14 - 3 + 2 = 13 novels.

2. Donated 7 and bought 4 novels. Thus, he had 13 - 7 + 4 = 10 novels.

3. Gives 4 to Joy and takes 5. Thus, he had 10 - 4 + 5 = 11 novels.

4. Gets 3 from Joy. Thus, he had 11 + 3 = 14 novels.

5. Gives 3 to Sanjay and gets 1 novel and 1 magazine. Thus, he had 14 - 3 + 1 = 12 novels and 1 magazine.

6. Gives the magazine to Rahul in exchange for a textbook. Thus, he had 12 novels and 1 textbook.

7. Gives the textbook to Joy and takes a novel. Thus, he had 12 + 1 = 13 novels.

8. Gives Rahul a novel and gets a magazine. Thus, he had 13 - 1 = 12 novels and 1 magazine.

Thus, Abeer does not have any textbooks.

Hence, the answer is option A.
