can I review the part hissing and rearing back, broadening the flesh behind its head the way a cobra does.[/i] as parallelism,

if can review as parallelism, then comma can be replaced with and, right?
if cannot review as parallelism, then what the different from parallelism?
The VERBing modifiers connected by a comma must be parallel and serve the same function, but do not attempt to replace the comma with and.

OA: hissing and rearing back, broadening the flesh
Here, the conveyed meaning is that the red actions are distinct from the blue action.
If we replace the comma with and, we get:
hissing and rearing back and broadening the flesh
Here, the conveyed meaning is that the three VERBing actions all happen together.
Not the intended meaning.
one more question
normally, prep + NOUN + Ving is incorrect in GMAT, in this case, it is correct, did i miss somthing?
would you please point out when prep + NOUN + Ving will be correct?

thanks a lot
have a nice day

PREPOSITION + NOUN + VERBing is a valid construction.
SC26 in the OG12:
over a period beginning a few years before Susan's marriage
Here, the portion in red = PREPOSITION (over) + NOUN (a period) + VERBing (beginning)

PREPOSITION + NOUN + VERBing is incorrect only if the meaning is distorted.
Incorrect:
I am impressed by John dancing.
Here, the intended meaning is that I am impressed by the DANCING, but the phrase in red implies that I am impressed by JOHN.
Correct:
I am impressed by John's dancing.
Here, it is crystal clear that John's DANCING is impressive.
