The leucine zipper motif functions to A. mediate the physical association of two polypeptides. B. anchor transcriptional activator proteins to enhancer sequences. C. release leucines from misfolded transcription factors. D. integrate leucines and isoleucines into newly translated transcriptional activators.

That's only because the leucine zipper symbol consisting of such a leucine remnant anywhere certain 7th point and has an α helical attachment.
Maybe the leucine including its zipper between one protein dimples again from α-helix as well as interdigit this same leucine including its iterator of some other antibody.

Some other possibilities in question are not connected to something like the situation in question So that is the correct approach.

ZIP or the leucine zipper motif is a series that contains periodic repetition of the leucine amino group at every seventh position of the array.

The correct option is:

Option A. mediate the physical association of two polypeptides.

This can be explained as:

ZIP forms the alpha-helical conformation that promotes dimerization and sometimes oligomerisation.

bZip allows protein dimerization by interdigitating two leucine of different helices of different molecules.

Therefore, ZIP moderates the physical linkage of polypeptides.
