Step-by-step explanation:

The test Randall did is called a Streak Test. By scratching a rock on unglazed porcelain, a small amount of dust or powdered mineral will be left behind on the plate. This small amount of powdered mineral is called a 'streak'.

ANSWER: The property being tested is B) Streak to identify the unknown mineral Randall has.
