The resting membrane potential of a neuron becomes less negative (e.g., shifts from -70 mV to -60 mV) during

A. Hyperpolarization
B. Repolarization
C. Depolarization
✓
D. The absolute refractory period

📝 Explanation

Depolarization refers to any shift in membrane potential toward a less negative (or more positive) value, generally caused by the influx of positive ions like sodium.
