Final answer:
In geometry, the name for a plane is typically a single letter, while multiple letters like EBD suggest points on the plane. EBD cannot be an acceptable name for plane Q as it does not follow the conventions for naming planes.
Step-by-step explanation:
The acceptable name for a plane in geometry typically consists of a single letter, often in italics or written with a special symbol, to denote its identity. When multiple letters are used, they usually refer to points that lie on that plane, and at least three non-collinear points are required to name a plane. Therefore, EBD is not an acceptable name for plane Q because EBD implies the names of points on a plane rather than the plane's unique designation, which is given by a single letter, Q in this case.
