The correct answer is option 3 - 7.
Structural variation in DNA reflects three things: the different possible conformations of the deoxyribose, rotation about the contiguous bonds that make up the phosphodeoxyribose backbone, and free rotation about the C-1' –N-glycosyl bond.
The conformation of a nucleotide in DNA is affected by rotation about seven different bonds. Six of the bonds rotate freely. The limited rotation about bond 4 gives rise to ring pucker, in which one of the atoms in the five-membered furanose ring is out of the plane described by the other four. This conformation is endo or exo, depending on whether the atom is displaced to the same side of the plane as C-5' or to the opposite side.
For purine bases in nucleotides, only two conformations with respect to the attached ribose units are sterically permitted, anti or syn. Pyrimidines generally occur in the anti conformation

Thank you for this question , let me help you in finding the answer.
The answer of your question is option 3 "7"
There are about 7 different bonds rotation which affects the conformation of a nucleotide in DNA. But out of these 7 , the number of freely rotating bond is 6 .the other one bonds rotation is not purely free.In this from the furanose ring one of the atom don't remain in regluar plane
