Explanation:

Question 91

To solve this, we analyze each option:

• Option a: Onychosis refers to any nail disorder or deformity, which matches the description of Moriah's condition.
• Option b: Onyx is a type of stone or a term for the nail plate in anatomy but not a disorder.
• Option c: Onychophosis is a specific nail condition (overgrowth), not a general term for deformity.
• Option d: Onychia is an inflammation of the nail matrix, not a general deformity term.

Analyzing each option:

• Option a: Infection is caused by pathogens, not sensitivity to harmless substances.
• Option b: Allergy is a reaction due to extreme sensitivity to normally harmless substances (allergens like foods, chemicals).
• Option c: Disease is a broader term for abnormal body function, not specific to sensitivity reactions.
• Option d: Parasite is an organism living on/ in another, not related to sensitivity reactions.

Analyzing each option:

• Option a: Hair Cuticle is the outermost layer of the hair shaft, made of overlapping scales. It creates shine and smooth feel by reflecting light and being smooth.
• Option b: Hair Medulla is the innermost layer, often absent in fine hair, not responsible for shine/smoothness.
• Option c: Hair Cortex is the middle layer, responsible for strength, color, and texture (not shine/smoothness).
• Option d: Arrector pili is a muscle, not a hair shaft layer.
