The is should be C, Im not 100% sure though...
I think the glycolysis occurs in the cytosol.

DNA and RNA have completely different purposes in us. DNA stores and transfers genetic information (Eye and hair colour, skin colour, etc..). RNA codes amino acids and makes proteins. DNA is double stranded while RNA is single stranded. DNA uses adenine, thymine, cytosine, and guanine; while RNA uses adenine, cytosine, uracil, and guanine.
It helps classify animals according to their needs.
Hope this helps!
