Final Answer:
The brain requires approximately 15 minutes of exposure to new information to build the necessary synaptic gaps for retention.
Correct Option: C. 15 min.
Step-by-step explanation:
The correct option is C. 15 min. Research in cognitive science suggests that effective learning and memory formation involve the creation of synaptic connections in the brain. The process takes time, and a duration of around 15 minutes allows for the establishment of these connections, contributing to better retention of information.
In detail, during this timeframe, the brain engages in activities such as encoding, where it processes and converts sensory information into a form that can be stored. The synaptic gaps, or synapses, play a crucial role in this process, acting as the points of communication between neurons.
By choosing **15 minutes** as the correct option, the answer aligns with the general understanding in cognitive science regarding the time required for the brain to effectively build the synaptic gaps necessary for information retention.
**Correct Option: C. 15 min.**
