How does the ribosome know how to make the protein.?

According to google

So the ribosome moves along way and many tRNA molecule transport the correct amino acid to make the correct sequence which is to be formed and only stops when mRNA shows 'STOP' codon. So there is a chain of polypeptide which is synthesised by copying the DNA and this is how proteins are made.

and for clarification t-RNA is transfer RNA and m-RNA is messenger RNA

Ithink it's c (70)

Dna strands are split apart to allow an opening for replication. the opening has two replication forks so synthesis goes toward them in 5' to 3' direction.
