I believe the answer might be A, since it seems like JS has multiple advantages over KS, but I’m a bit uncertain about the specifics.

I feel like the normalization aspect of JS versus KS was discussed in class, but I can't remember if JS is actually normalized or not.

I remember that JS distance is often preferred because it doesn't require manual thresholds, but I'm not sure if that's the only reason.
