Final answer:
The majority of words in the list are related to the origin or composition of sediments, except for C. cosmogenous which refers to materials from outer space.
Step-by-step explanation:
The majority of words and phrases in the list A. biogenous, B. calcareous, C. cosmogenous, D. hydrogenous, and E. lithogenous are related to the origin or composition of sediments. They all describe different types of sedimentary materials. However, the word that does not fit this pattern is C. cosmogenous, as it refers to materials that originate from outer space rather than being directly related to sedimentation processes.
