Neuron is to brain as neighborhood is to city. A neuron is part of a brain, there need to be lots of them in order for the brain to function and to be a brain, much like there are many neighborhoods within a city. It cannot be A, as a poster is not necessarily always going to be propaganda, while a neuron is always a necessary part of a brain. It cannot be c, because an axle is part of a car, not the other way around, and it cannot be d, as faux pas are not always part of conversations and are unnecessary. Hope this helps!!
