Dear Friends,

I was having problems in answering the following question.

Like the thorny ballooning of a frightened pufferfish or the sudden appearance of angry sapphire hoops for which the blue-ringed octopus is named, so the California newt's display of its red underbelly is a clear warning that predators ignore at their peril.

(A) so the California newt's display of its red underbelly is a clear warning that predators ignore at their peril
(B) so it is at their peril that predators ignore the California newt's display of its red underbelly, a clear warning
(C) the California newt's displaying its red underbelly is a clear warning for predators, so they ignore it at their peril
(D) the California newt's display of its red underbelly is a clear warning that predators ignore at their peril
(E) it is at their peril that predators ignore the California newt's display of its red underbelly, a clear warning


Please help.

OA after some discussions.

Regards
Deano.
