Select the correct statements

Black color ppt of copper oxide is produced by the decomposition of the copper carbonate. So the compound A is basic copper carbonate while compound B is CuO.

CuO decomposes to release oxygen when heated. In this ${\mathrm{Cu}}_2\mathrm{O}$ is formed with compound D as a paramagnetic compound.

Here, all the options are correct.
