The hognose snake puts on an impressive bluff, hissing and rearing back, broadens the flesh behind its head the way a cobra does, feigning repeated strikes, but, having no dangerous fangs and no venom, eventually, if its pursuer is not cowed by the performance, will fall over and play dead.

broadens the flesh behind its head the way a cobra does and feigns repeated strikes, but with no dangerous fangs and no venom,
broadening the flesh behind its head the way a cobra does and feigning repeated strikes, but it has no dangerous fangs and no venom, and
broadening the flesh behind its head the way a cobra does and feigns repeated strikes, but with no dangerous fangs and no venom, and
broadening the flesh behind its head the way a cobra does, feigning repeated strikes, but with no dangerous fangs and no venom, and
1.here, "broadening ... and feigning ..." can be interpreted as a modifier of the previous action!
2.
in both A and B, you have three verbs (puts..., broadens..., will fall...).
there are exactly two ways to put 3 things into a list in the english language:
• X, Y, and Z
• X, Y, or Z
...and that's it.
there's no such construction as "X, Y, but Z", so, both of the first two choices are gone.
