Question

Hydrogen sulfide is associated with

B) The presence of strongly burrowing animals in sediments

Hydrogen sulfide is typically found in environments where oxygen is absent, such as in the pore waters of sediments. This is because it is produced through the anaerobic decomposition of organic matter by bacteria.
