c.

A straight-down CGM trend arrow means your glucose is falling quickly (rapidly decreasing). That signals a risk of hypoglycemia soon, so check your number and follow your diabetes-care plan — for example, treat if you’re near/under target (commonly with ~15 g fast-acting carbs and recheck in 15 minutes), or pause/adjust insulin delivery if you use a pump and that’s part of your plan. If you’re unsure, contact your care team.
