A molecular archivist in a deep-space habitat is synthesizing double-stranded DNA filaments to encrypt navigational records. She constructs a primary data strand with the sequence 5'-AGCTAGTC-3' and prepares to synthesize its matching partner strand. Which of the following correctly identifies the sequence, orientation, and total number of hydrogen bonds holding this eight-base-pair segment together?

A) 5'-TCGATCAG-3' with a total of 20 hydrogen bonds

B) 3'-TCGATCAG-5' with a total of 20 hydrogen bonds

C) 3'-TCGATCAG-5' with a total of 16 hydrogen bonds

D) 5'-GACTAGCT-3' with a total of 24 hydrogen bonds
