continuous variable
categorical variable

Explanation:

A time - series plot is used to show how a variable changes over time. The variable used in a time - series plot needs to be a quantitative variable because we are interested in measuring the magnitude of the variable at different time points. Qualitative (categorical) variables are used to represent categories and are not suitable for showing changes over time in the context of a time - series plot. Among the options, "quantitative variable" is the correct choice as it can take on numerical values that can be measured and tracked over time.

Answer:

A. quantitative variable
