Answer:
DNA
Explanation:
RNA is not a double helix
Uracil is on the RNA, this is a picture or DNA. Uracil is just one of the nucleic bases
This is not a monomer; it's actually a polymer
It is DNA because it is a double helix structure held together by the four nucleic bases.

Answer:
Option B , Binding Energy
Explanation:
The energy in combining two nucleus is lost in binding them. This binding energy is too large that it causes significant loss of mass and is calculated using the Einstein’s theory of relativity.  
When two nucleons combine , mass defect is caused which leads to loss of mass associated with energy and therefore the mass of nucleus is less than the mass of nucleons.  
Hence, Option B is correct.
