Possible Answers:

  2. Unusual algae growth
  3. White froth
  4. All of these

The Correct Answer:

D. Sensory clues to the possible presence of hazardous materials in water include Dead fish, Unusual algae growth, and White froth.

Explanation:

Sensory cues are considered to detect the presence of any hazard. These are the least potential and dependable ways of identifying any danger or trouble. The majority of the material does not have any kind of warning signals like taste or smell.

Skin irritation,  watery eyes, feelings of nausea, cough, etc., are a few of the sensory clues. These sensations can be due to the white frock, unusual algae growth,  dead animals, etc.  Even if you see them in water bodies, then the water can be potentially dangerous to intake/drink.
