Final answer:
Option 1.
Limestone is a chemical sedimentary rock composed primarily of calcite and aragonite, often containing fossilized marine organisms.
Step-by-step explanation:
The chemical sedimentary rock referred to in the question is best represented by limestone. Limestone is primarily composed of calcite and aragonite, which are different forms of calcium carbonate.
It often contains fossilized remains of marine organisms, making it common to find fossils embedded in limestone.
Other sedimentary rocks mentioned, such as sandstone, are clastic, formed by the accumulation of sand-sized minerals and rock fragments.
Granite is an igneous rock, formed from solidifying molten rock, and marble is a metamorphic rock that originates from the transformation of limestone under high pressure and temperature.
Therefore, the option that represents a kind of chemical sedimentary rock is limestone.
Please mention the correct option in the final answer: 1) Limestone.
Final answer in 20 words: The type of chemical sedimentary rock is limestone, which is primarily composed of calcite and often contains fossils.
