A) He reveals his location to highlight the injustice of the situation.
<span>Boo Radley is very reclusive and hardly ventures out into the world at all. We don't know exactly why this is, although as far as we can tell, the treatment by his family has contributed to it. It seems he is motivated by his fear of the outside world to live as recursively as he does, but his interactions with Scout and Jem show a different side. He is very caring and protective of them, although, ironically, they don't realize this for a long time and persist in fearing him as some kind of monster. He comes to function as a symbol of basic goodness and innocence, in contrast to society at large which is shown to be riddled with hypocrisy and prejudice.He is outside society and free from its vices. He is motivated by compassion and does not look for rewards. Ultimately, and crucially, he helps Scout to realize that, in spite of many grim events in the course of the novel, there is still goodness in the world.
I hope this helps!</span>
