Read the following excerpt from The Jungle Book by Rudyard Kipling. And he grew and grew strong as a boy must grow who does not know that he is learning any lessons, and who has nothing in the world to think of except things to eat.

Mother Wolf told him once or twice that Shere Khan was not a creature to be trusted, and that some day he must kill Shere Khan; but though a young wolf would have remembered that advice every hour, Mowgli forgot it because he was only a boy—though he would have called himself a wolf if he had been able to speak in any human tongue.

Which detail adds tension to the rising action of the story?

Mowgli grows stronger and learns life lessons without knowing it.
Mother Wolf tells Mowgli that some day he will have to kill Shere Khan.
Mowgli forgets his mother’s advice because he is a young boy.
Mowgli would call himself a wolf if he had the ability to speak like a human.
