It should be the last one, but if you can pick more than one answer then I would do the first and last one but I’m confident that it would be the last one either way :) hopefully this is helpful
Answer:
The bonds that are formed between nitrogenous bases are Hydrogen Bond.
Explanation:
When a hydrogen atom interract with an electronegative atom such oxygen,fluorine hydrogen bond forms,
A single hydrogen bond is weak noncovalent bond but collectively they exerts very strong interraction.
Hydrogen bonding occurs between complementary base pair .For exam An adenine base forms 2 hydrogen bonds with thymine base whereas guanine forms 3 hydrogen bonds with cytosine base.
The hydrogen bonding between complementary is very much important to stabilize the structure of DNA .
