The complementary base pairs of guanine with cytosine and adenine with thymine connect to one another using hydrogen bonds. In addition to holding the DNA strands together, the hydrogen bonding between the complementary bases also sequester the bases in the interior of the double helix. Since, the option of Guanine and Cytosine is not provided. Hence, the correct option is Option C.

Double Hydrogen Bond in DNA
Double hydrogen bonding is a type of chemical bond that occurs between two nucleotide bases in DNA. It is an important feature of DNA and is responsible for maintaining the stability and integrity of the double helix structure of DNA. The double hydrogen bond occurs between adenine and thymine in DNA.
Adenine and Thymine
Adenine and thymine are two of the four nucleotide bases that make up DNA. Adenine is one of the purine bases, and thymine is one of the pyrimidine bases. The two bases are complementary to each other, meaning that adenine always pairs with thymine in DNA.
Structure of Double Hydrogen Bond
The double hydrogen bond between adenine and thymine in DNA is formed by two hydrogen bonds. One hydrogen bond is formed between the N1 nitrogen atom of adenine and the C6 carbonyl oxygen atom of thymine. The other hydrogen bond is formed between the N6 nitrogen atom of adenine and the O2 carbonyl oxygen atom of thymine.
Importance of Double Hydrogen Bond
The double hydrogen bond between adenine and thymine in DNA is important because it helps to maintain the stability and integrity of the double helix structure of DNA. Without the double hydrogen bond, the two strands of DNA would not be held together as strongly, and the DNA would be more prone to breaking or unraveling.
Conclusion
In conclusion, the double hydrogen bond is an important feature of DNA that occurs between adenine and thymine. It is formed by two hydrogen bonds and helps to maintain the stability and integrity of the double helix structure of DNA.

Adenine and Thymine pairs with 2 hydrogen bonds while Guanine and Cytosine pairs with 3 hydrogen bonds. A=T(2 bonds) That's why A=T is less stable than G =_C(3bonds)
