All what the word tetravalent means is that carbon can form 4 chemical bonds, due to the fact that carbon has 4 unpaired valence electrons in its furthest shell, which can be used to bond to other atoms, to form linear and cyclic structures in organic compounds.
Tetravalent also tells us indirectly what the molecular geometry of the atom would be if bonded to those number of bonds, if 4, then it would be tetrahedral and have bond angles of 109.5.
The right answer is D.
A codon is a sequence of three nucleotides on a messenger ribonucleic acid (mRNA) specifying one of the 22 proteinigenic amino acids whose succession on the messenger RNA determines the primary structure of the protein to be synthesized. As the messenger RNAs consist of a succession of several tens to several hundreds of nucleotides, it is also several tens to several hundreds of amino acids that can thus be assembled linearly to form protein chains.
