Answer:
Connections that are used will be strengthened.
Step-by-step explanation:
Synaptic pruning is the mechanism for destroying underused synapses, making room for new connections so we can learn for a lifetime. In other words, synaptic pruning would be the destruction of several minor synapses, providing fine regulation of the nervous system that excludes redundant systems. Thus, we can state that during Darren's brain development, after his mother promotes synaptic pruning, the connections used will be reinforced.
