Explanation for each option:

A. Examining the relationship between variables with the purpose of determining whether and how two variables change together - This describes correlational research, which focuses on identifying relationships between variables and understanding how they may change together. It does not fit the definition of descriptive research.

B. Determining the basic dimensions of a phenomenon and defining what it is or how often it occurs; but it cannot provide causal information - This is the correct description of descriptive research. Descriptive research aims to accurately and systematically describe a population, situation, or phenomenon. It focuses on the "what" aspect, such as the frequency or characteristics of a phenomenon, without delving into the "why" or "how."
