Explanation:

In the context of hazardous materials and safety (related to Natural Science, specifically areas like Chemistry or Safety Science), the most common route of entry for hazardous substances into the human body is inhalation. This is because airborne particles, gases, or vapors can easily be breathed in, and many workplace or environmental hazards are present in the air. Ingestion (eating/drinking), injection (through needles or wounds), and absorption (through skin) are less common as primary routes compared to inhalation in typical exposure scenarios.

Answer:

c. Inhalation
