Helen wants to prevent her staff from sideloading applications to their Android devices. What type of tool is best suited to preventing this type of issue without reducing other functionality for the device?

A mobile device management (MDM) solution will allow settings and software to be managed centrally, allowing Helen to both control sideloading permissions and to prevent unwanted applications from being installed. Disabling either the hardware vendor or Google's store does not prevent sideloading from an external media like a microSD card, which can reduce the functionality of devices. An EDR is helpful to identify malicious software but doesn't manage devices and prevent sideloading.
