The environment that would most likely not contain fossils is **intrusive rock formed from cooled magma**.
Intrusive rocks are formed from molten magma that cools and solidifies below the Earth's surface, and this process typically does not preserve organic material. In contrast, the other environments listed (cracked dried mud, sediment in a sandy river bed, and layers of sand) are all more likely to contain fossils because they represent sedimentary environments where organic material can be buried and preserved over time.
