the answer is B. the second one
When DNA was discovered, Watson and Crick saw that the strands of the double helix are lined up in the opposite direction of each other. This type of orientation is called the antiparallel orientation.
The antiparallel orientation is a type of orientation showing two polymers present side by side but running in the opposite direction. The best example of this is the deoxyribo nucleic acid (DNA). DNA molecule is made up of a pair of polynucleotide strands which are antiparallel. The antiparallel orientation of the DNA facilitates the hydrogen bonding between the two complimentary strands. This is also important for the processes of DNA replication and transcription.
