Explanation:

Question 67

• Option a: Contusion is a bruise from blunt force, not from bacterial invasion.
• Option b: Antitoxin is a substance that counteracts toxins, not a result of bacterial invasion.
• Option c: Abrasion is a scrape, not related to bacterial invasion.
• Option d: Infection is the invasion and multiplication of pathogens (like bacteria) in body tissues, which matches the description.

• Tinea pedis is the medical term for Athlete's foot, a fungal infection of the feet. Option b describes a nail condition (maybe onychomycosis - related but not tinea pedis), option c is a symptom but not the name of the condition, option d is ingrown nails which is different.

• Option a: Density refers to the number of hair strands, not moisture absorption.
• Option b: Porosity is the hair's ability to absorb and retain moisture, which fits the description.
• Option c: Elasticity is about hair's ability to stretch and return, not moisture absorption.
• Option d: Saturation is the state of being soaked, not the ability to absorb.

Answer:

d. infection
