Options

  1. AThe number of parts of the component divided by 1,000,000
  2. BThe number of parts of the component multiplied by 10
  3. CThe number of parts of the component divided by 6
  4. DThe total number of parts of all components divided by 1,000,000

Correct answer

A. The number of parts of the component divided by 1,000,000

Step-by-step solution

The paragraph defines "Parts per million (ppm)" as the number of parts of the component divided by 1,000,000.
