The correct answer is: D. a-3, b-2, c-1, d-4.
Butadiene is a hydrocarbon that is used to make synthetic rubber. It is also used to make other chemicals, such as styrene and butadiene-styrene copolymers. Lead tetraethyl is a gasoline additive that prevents engine knocking. It is also used in other applications, such as in the manufacture of lead-based paints. Phosphorus is a non-metallic chemical element that is found in nature in both organic and inorganic forms. It is used in a variety of applications, such as in the manufacture of fertilizers, pesticides, and matches. Aniline is an organic compound that is used to make dyes, drugs, and other chemicals. It is also used in the manufacture of explosives.
Here is a brief explanation of each option:
- Option A: a-2, b-1, c-3, d-4. This option is incorrect because it pairs butadiene with the match industry. Butadiene is used to make synthetic rubber, not matches.
- Option B: a-3, b-4, c-1, d-2. This option is incorrect because it pairs lead tetraethyl with the dye industry. Lead tetraethyl is used as a gasoline additive, not in the manufacture of dyes.
- Option C: a-1, b-2, c-3, d-4. This option is incorrect because it pairs phosphorus with the petroleum industry. Phosphorus is not found in petroleum, but it is used in the manufacture of gasoline additives.
- Option D: a-3, b-2, c-1, d-4. This option is the correct answer because it pairs butadiene with the rubber industry, lead tetraethyl with the gasoline industry, phosphorus with the match industry, and aniline with the dye industry.
