An animator with no knowledge of bitmap or vector could encounter some issues
Explanation:
For example, if an artist was working with a bitmap when they should have been working with vector, they would not be able to scale up the image, especially if they didn’t know how to convert the images from bitmap to vector. Also, they might have difficulty publishing vector images, because the internet mostly uses bitmap.
A Bongo drum is not included in a drum set. So the answer is B. I don't play drums, but it makes sense being as a bongo drum doesn't seem to belong in a band. I hope I helped :).
