What is the purpose of the fibers in grease? a. it's the actual lubricating element in the grease. b. it prevents the lubricant from evaporating. c. it traps the lubricant and holds it in suspension. d. it thins the grease.

Option D:The purpose of fibers in grease is to thin the grease

Explanation:

The fibers especially synthetic types are malleable. This feature makes them suitable for grease that tends to thin or align their surface material in a desired form.

In most grease pomade, fibers are added to align with your hair in order to  provide malleability effect. This effect makes the hair thread out thinly in desired direction and maintain suspension of the hair's strands and form.

After the application of fibrous grease(say Japanese fiber grease pomade) for instance on the hair, the hair becomes malleable and you can easily see threads of thin hair straightening up as you comb.
