Everyone knows a guy like Jared: the burnout kid in high school who sells weed cookies and has a scary mom who's often wasted and wielding some kind of weapon. Jared does smoke and drink too much, and he does make the best cookies in town, and his mom is a mess, but he's also a kid who has an immense capacity for compassion and an impulse to watch over people more than twice his age, and he can't rely on anyone for consistent love and support, except for his flatulent pit bull, Baby Killer (he calls her Baby)--and now she's dead.
Jared can't count on his mom to stay sober and stick around to take care of him. He can't rely on his dad to pay the bills and support his new wife and step-daughter. Jared is only sixteen but feels like he is the one who must stabilize his family's life, even look out for his elderly neighbours. But he struggles to keep everything afloat...and sometimes he blacks out. And he puzzles over why his maternal grandmother has never liked him, why she says he's the son of a trickster, that he isn't human. Mind you, ravens speak to him--even when he's not stoned.
The character Mowgli was nurtured, just not by humans. Therefore, it is not answer C. Also, he was not "rejected by society" or an "outcast" so it is not A or B. The answer is D. Mowgli is a man who has grown up according to the rules and customs of the jungle, as it says, BUT even though he is a man, his ideas of etiquette and communication are those of animals, rather than people. Because of this, Mowgli does not understand "the law of men" which refers to how humans behave, which causes him to not be able to "fit in" with society. It's basically a cultural barrier. The whole theme of the story is that he is still human, even if his way of life is different. Sometimes, certain cultures look down upon others because they have different customs, which is rude and ignorant. This story has a theme of recognizing people as humans in spite of cultural differences.
