Hey there! I'm happy to help!
Much of Utah used to be covered by a prehistoric body of water called <u>Lake</u> <u>Bonneville</u>. Evidences of this include fossils of trilobites and fish in Utah's mountains.
Sedimentary rocks are comprised of sediments (small bits and pieces of weathered rock), and the reason sedimentary rock formations are usually layered is because they were formed underwater. The pressure of the water compacts the rocks, and as new sediments arrive in the water, it is compacted on top of the previous compressed rock, creating layers.
Since we know that much of Utah used to be a lake, the best explanation for this sedimentary rock limestone is that A. Western Utah used to be under water (an ocean or inland sea).
Have a wonderful day and keep on learning! :D
