friendship
Option C.
Step-by-step explanation:
The passage talks about a boy and a little girl who did not even know each other but spent time together in the recess and had a good and comfortable company with each other. This girl had such an impact that the narrator would never forget her.
It was a very strange kind of friendship where not even knowing each other the two spent time together, maybe leading to the beginning or start of a new friendship.
