Which of the following describes the fundamental distinction between vector graphics and raster (bitmap) graphics?
Option B is correct. Vector graphics use mathematical formulas (points, lines, curves) scaling without quality loss, whereas raster graphics use a grid of pixels which lose quality when enlarged.

Option A is correct. 40 kHz (At least double the highest frequency component)
Which image file format supports lossy compression, 24-bit color depth (16.7 million colors), but does NOT support transparency (alpha channel)?
