C. Paleobootany
D. Palantiology

Answer

To determine the existence of coal and petroleum, we can follow these steps:

### Step 1: Understanding Coal and Petroleum
Coal and petroleum are fossil fuels formed from the remains of ancient plants and animals. Their existence is linked to specific geological and ecological conditions that existed millions of years ago.

### Step 2: Study of Fossils
Fossils are the preserved remains or impressions of ancient organisms. By studying fossils, we can gain insights into the types of plants and animals that existed in the past, which contributed to the formation of coal and petroleum.

### Step 3: Examination of Sedimentary Rocks
Coal and petroleum are typically found in sedimentary rocks. These rocks are formed from the accumulation of sediments over time, often in environments that were once underwater or covered in vegetation. By examining these rocks, geologists can identify layers that indicate the presence of organic material.

### Step 4: Analyzing Geological History
Geologists study the geological history of an area to understand the conditions under which coal and petroleum formed. This includes analyzing rock layers, the types of sediments, and the age of the rocks.

### Step 5: Ecology and Environmental Conditions
The study of ecology helps us understand the environmental conditions that led to the formation of coal and petroleum. This includes the types of ecosystems that existed, such as swamps and forests, which provided the organic material necessary for fossil fuel formation.

### Conclusion
In summary, the existence of coal and petroleum can be known from the study of fossils, sedimentary rocks, geological history, and ecological conditions.
