<u>Answer:</u>
 is an inorganic compound.
 is an inorganic compound.
<u>Solution:</u>
- Firstly, all the known definitions of organic compounds excludes Carbonic acid and it's salt from organic compounds except if 'C' is present in the cation.  
- Secondly, Sodium is a metal which organic compounds cannot posses as a compound.  
- Lastly, there is absence of C-H bond which is present in all the organic compounds.
Hence, we can conclude that  is an inorganic compound though there is presence of Carbon atom in it.

Answer:
The correct answer is D)RNA polymerase
Explanation:
In DNA replication many enzymes and proteins are required to replicate a DNA template. For initiation of DNA synthesis the two DNA strands must be separated which is done by helicase.
Then primase adds short nucleotide sequence and initiate DNA replication. After that DNA polymerase acts and adds nucleotide at the 3' end of growing  DNA strand. Ligase is the enzyme that joins the two Okazaki fragments that are created in the lagging strand.
RNA polymerase is not required in DNA replication and it works in transcription therefore the correct answer is RNA polymerase.
