Answer:

C If the child already had the antibodies to fight the bacteria

Explanation:

There are a lot of bacteria that we have already storage antibodies for, our immune system is like a database of antibodies that learns with every disease we get, some of them won´t even manifest, because our immune system is strong and produces enough antibodies to counterattack the germs. So from the options given, the most reasonable and possible is that the kid already had the antibodies to fight that bacteria.
