c. Two hairs from the same head may not have the same morphological characteristics.  

Explanation:

As hair grows in humans, it contains three internal parts:

1. the cuticle,

2. the cortex,

3. the medulla.

Cuticle :  The cuticle is the outermost part and is made of scales.

Cortex :   The cortex is in the middle and made of protein.

Medulla : In the very middle is the medulla. It supports the hair's structure.

Hair is made of a protein called keratin.

Melanin gives hair its color.

The longest hair in the human body is the head hair. No two head hair may have the same morphological characteristics.

Thus the answer is

c. Two hairs from the same head may not have the same morphological characteristics.
