B.
Plants and animals are both autotrophs.
C.
Plants and animals are both heterotrophs.

This is due to the characteristic of specificity of the enzyme. Enzymes have active sites that only bind particular substrates which they catalyze. This is because the shape of the active site is complementary to that of the substrate (like lock and key).
Messenger RNA (mRNA), molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes).
