B.
Bonds between the strands require oxidation and bonds within the strands require reduction.
C.
There are fewer bonds between the strands than within the strands.

The correct answer is:
**D. Bonds between the strands are relatively weak hydrogen bonds, whereas bonds within the strands are relatively strong covalent bonds.**
This distinction is important because the hydrogen bonds between the two strands of DNA can be easily broken by enzymes during processes such as DNA replication, allowing for the strands to separate without breaking the stronger covalent bonds that hold the sugar-phosphate backbone of each strand together.
