Answer: Option (d) is the correct answer.
Step-by-step explanation:
A streak is able to absorb light that is hitting or falling on it. This is because streak has small particles due to which upon absorption of light particles of streak appear dark in color.
A mineral is rubbed on a streak and particles of mineral deposit on the streak. Therefore, when light falls on it then it absorbs light and reflects the color of mineral.
Hence, a streak is able to determine the true color of a mineral.
