You can check the Periodic Table of Elements to see that Li and Ca are elements and cannot be broken down. The correct answers are B and D.
Have a good day.

\huge\boxed{\textsf{Li and Ca}}

An element is a substance that can't be broken down further. Lithium (Li) and calcium (Ca) are examples of elements.

Carbon monoxide (CO) and potassium bromide (KBr) are examples of compounds, which are made up of more than one element put together.
