Answer: (C)

Dimensions are the descriptive attributes that categorize your data in Google Analytics. They tell you the “what” and the “where” of what you’re analyzing—things like where users came from (source/medium), which device they used (device category), which page or screen they viewed, or which event happened. They’re qualitative, not numbers, and they’re used to segment the numeric measurements you collect.

Metrics are the actual numbers you measure, such as sessions, users, pageviews, or revenue. By grouping these metrics by a dimension, you can see, for example, how many sessions came from each traffic source or how device type relates to conversions.

So, dimensions describe attributes of the data to help you break down the metrics, while numerical values themselves are the metrics.
