Explanation

Number of defective units is attribute data because it represents a count of items classified into a category (defective vs. non-defective) - no measurement instrument is needed, just a yes/no judgment per unit.

Options A (time), B (temperature), and D (length) are all variable (continuous) data - each requires a measuring instrument and can take any value along a continuous scale, making them fundamentally different from counted, categorical data.

Memory tip: Think "Attribute = Count, Variable = Measure." If you need a ruler, thermometer, or stopwatch, it's variable data. If you're simply tallying items that pass or fail a condition, it's attribute data.
