Explanation:

• Analyze each option:
• "the mass per unit volume of a material" defines density, not mass.
• "anything that takes up space" describes volume - related to matter but not mass.
• "anything that takes up space and has mass" defines matter, not mass.
• "a measurement of the quantity of matter in an object" is the correct definition of mass.

Answer:

D. a measurement of the quantity of matter in an object (assuming the last option is D; if options are labeled differently, adjust the label but keep the text)
