Step 1 of 2

Step 2 of 2

Answer 1

Casts:

Casts are cylindrical in structure formed in kidney and found in urinary sediment.

Hair and fibers:

Hair, fibers in diapers and clothes are mistaken with casts. Though they are more refractile and longer than casts.

• Discrimination between casts and fibers can be done with polarized light.

• Casts do not polarize whereas fibers have ability to polarize.

Therefore, casts and fibers are differentiated using “polarized light”. Hence, the correct answer is option $<div class=answer> Casts: Casts are cylindrical in structure formed in kidney and found in urinary sediment.
