Correct answer: C — Hybrid closed-loop insulin pump system (automated insulin delivery) with predictive low-glucose suspend

Hybrid closed-loop systems (automated insulin delivery) with predictive low-glucose suspend features significantly reduce hypoglycaemia, especially nocturnal, and improve time in range. They are particularly beneficial for patients with impaired hypoglycaemia awareness. These systems automatically adjust basal insulin delivery based on CGM readings.
