To answer the question of which substance is formed as a result of the compaction of dead plants, we need to consider the geological processes involved in the formation of fossil fuels and other natural resources.

1. Understanding the Materials:

   • Dead plants undergo a series of geological processes over millions of years.
   • The remains of these plants are typically found in swampy areas where they accumulate and are buried by sediment.

2. Types of Fossil Fuels:

   • Coal: Formed primarily from the compaction and transformation of plant material, particularly in swamp conditions, leading to carbonization.
   • Petroleum and Natural Gas: These are primarily formed from the remains of microscopic marine organisms, not plants.

3. Compaction Process:

   • The process of compaction involves the pressure of overlying sediment compressing the accumulated plant material, leading to the formation of coal.

Given these points, the correct answer is D. Coal, as it specifically results from the compaction of dead plant material over time.
