Pls ! limestone is an example of a. a clastic sedimentary rock b. breccia c. a biochemical sedimentary rock d. a conglomerate

The correct answer for the blank is-  C) a biochemical sedimentary rock.

Biochemical sedimentary rocks are a type of sedimentary rocks, which are formed through organic processes that involve production of sediments with the help of living organisms.

These living organisms can include snails and clams, which discard their shells composed of calcium carbonate so as to form limestone in a biochemical sedimentary rock.

Thus, limestone is an example of a biochemical sedimentary rock.
