Answer:
Organs of excretion make up the excretory system. 
They include the :
kidneys-Blood by-products are filtered out by the kidneys and leave the body in urine form. They are part of the urinary system, which also includes the ureters, bladder, and urethra
 large intestine-By-products enter the intestine and leave the body in the form of feces
 liver- breaks down harmful substances. It's by-products are excreted into bile or blood.
 skin-Sweating eliminates excess water and salts, as well as a small amount of urea, a byproduct of protein catabolism
lungs- oxygen is exchanged for a waste gas called carbon dioxide. Your bloodstream then carries this waste gas back to the lungs where it is removed from the bloodstream and then exhaled
Hope this helps!!!!!!

Information is encoded in DNA, then copied onto RNA during transcription. Then, ribosomes convert the information carried in RNA into a protein, in the process of translation. Also, A and D could be ruled out because DNA and RNA are solely involved with proteins, but polysacchariades are chains of sugars.
