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 in infants involves producing far more connections than needed first. Through experience and development, unused connections are eliminated (pruned) to refine neural pathways, while frequently used connections are strengthened. Options a, b, and c are incorrect: synapses are not developed only when needed, we are not born with the exact number we need, and excess connections are not maintained until adulthood.

Answer:

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