Q
How are vertices and faces typically defined in WebGL geometry?

Answer & Solution

Answer: Option A
Solution:
Vertices and faces in WebGL geometry are typically defined using arrays of coordinates (vertices) and indices (faces), specifying the geometry and structure of 3D objects to be rendered.
