what mouse command allows users to zoom in and out of the model?
○ lmb + hold drag
○ rmb + hold drag
○ ctrl + lmb + drag
○ scroll mmb

Explanation:

In many software applications (especially those related to 3D modeling or CAD), scrolling the middle mouse button (MMB) is a common command for zooming in and out of a model. LMB + hold drag is often for panning or selecting, RMB + hold drag might be for rotating or accessing context menus, and Ctrl + LMB + drag could be for a different kind of manipulation (like adding to a selection in some cases).

Answer:

scroll MMB
