Solution

The correct option is A \N
In a DNA double helix, adenine pairs with thymine by two hydrogen bonds while guanine pairs with cytosine by three hydrogen bonds.

In the given DNA segment, each base is linked to its complementary base by two hydrogen bonds. This indicates that the bases are adenine and thymine. There are no cytosine and guanine bases found in the given segment.
