a we develop all synapses as we need them
b we are born with the exact number of synaptic connections that well need
c an infant overdevelops synaptic connections and maintains these connections until adulthood
d an infant overdevelops synaptic connections and then prunes away connections that are not needed as they develop

Explanation:

Synaptic development follows a pattern where infants produce an overabundance of synapses early in development. As they grow and interact with their environment, unused or unnecessary synapses are eliminated (pruned) to refine neural pathways, which supports efficient brain function. Options a, b, and c are incorrect: synapses are not only developed "as needed," we are not born with our full required set, and excess synapses are not maintained until adulthood.

Answer:

d. An infant overdevelops synaptic connections and then prunes away connections that are not needed as they develop
