Correct answer: B. Foraminferans
- A. Zooflagellates
- B. Foraminferans
- C. Aetinopods
- D. Apicomplexans
Explanation
Foraminiferans have calcium carbonate shells, and the accumulated shells and remains of these organisms contribute substantially to limestone deposits. Actinopods may have mineral-like skeletons, but their deposits are not the main source referred to here.
