Answer:
B. MILC
Step-by-step explanation:
MILC stands for Mirrorless Interchangeable-lens Camera, they are also called DSLM (Digital Single Lens Mirrorless), is a camera that uses a digital display system, and the camera doesn't have an optical mirror or viewfinder like a conventional Digital Single-lens Reflex Camera (DSLR).
The statement says that Betty told her family that her new camera worked as a DSLR camera but didn't have a moveable mirror system.
So, option A) SLR and E) Analog are incorrect, as they aren´t digital cameras.
Options C) Point and shoot and D) Fixed-lens are incorrect as they don´t have interchangeable lenses.
