Which product uses the most silver as an ingredient ?

Camera Film
-
Tooth
-
Rollers
-
None of the Above
A
Correct answer
Explanation
Traditional camera film (photographic film) uses silver halides (silver bromide, silver chloride) as light-sensitive compounds, making it the largest user of silver among consumer products. This question has minor errors - 'Tooth' should likely be 'Toothpaste' (which may contain silver compounds), and 'Rollers' is vague (possibly refers to roller bearings).
