Raster is to vector as ____ is to ____.

A. pixel;primitive
B. software;camera
C. scale;size
D. prototype; wireframe

A. pixel;primitive

A. pixel; primitive

The correct answer is A. pixel;primitive.

To understand why, let's break it down:

Raster and vector are two different ways of representing graphics.

Raster graphics, also known as bitmap images, are made up of a grid of pixels. Each pixel contains specific color information, and when combined together, they form the image. Common file formats for raster graphics include JPEG, PNG, and GIF.

On the other hand, vector graphics use mathematical equations and shapes to define an image. Instead of being made up of pixels, they are composed of paths, curves, and geometric shapes. Vector graphics can be scaled up or down without losing quality. Common file formats for vector graphics include SVG, AI, and EPS.

The analogy given in the question is comparing raster and vector to another pair, so we need to find the option that represents two similar concepts.
Option A, "pixel;primitive," matches this analogy because a pixel is the smallest unit of a raster image, and a primitive is the smallest building block in vector images.
