Molecule A contains the a. starch necessary for ribosome synthesis in the cytoplasm b. organic substance that is broken down into molecules B, C, and D c. proteins that form the ribosome in the cytoplasm d. directions for the synthesis of molecules B, C, and D

The question is incomplete as it does not have the figure which is provided in the attachment

D. directions for the synthesis of molecules B, C, and D

Explanation:

In the given question, the figure illustrates that there is a molecule present inside the nucleus which could form the different or other molecules through the ribosomes like the receptor molecules, the enzymes, and the hormones.

This shows that a single molecule A has the guidelines to form all of these other molecules through ribosomes.  The molecule A inside the nucleus which contains all the guidelines for the synthesis of different molecules is known as DNA.

Thus, the selected option is correct.
