C. Protein.
DNA is nothing if it cannot be transcribed into protein. Ribosomes are just mechanism for protein making and by its own, it is just a form of machinery. RNA is similar to DNA.

I don't really get your question with the whole serves to interact with the world thing. But, every cell needs proteins to live. So, I'd guess proteins. DNA holds the genes to make the proteins. Since DNA must stay in the nucleus, RNA is needed. RNA is transcribed and then heads out of the nucleus into the cell. The nucleus doesn't allow anything with thymine get out, that is why RNA replaces it's thymine with uracil. So, then the RNA is translated to make a protein. Ribosomes are organelles that make proteins.

Don't understand ur question...but i'll say (c) protein (a, b, and d all lead upto proteins in the end anyway!)

Odd question, but I'd say proteins.
