Explanation

A swollen (expanded) battery is a serious safety hazard. Lithium-ion batteries swell due to internal chemical breakdown, which can lead to thermal runaway, fire, or explosion. The immediate priority is to power off the device to stop electrical current flow and heat generation, reducing the risk of further damage or injury. Checking health status (Option B) is a later step. Replacing the SIM card (Option A) and disabling VPN (Option D) are irrelevant to this safety emergency.
