-
Instead of

-
Even when
-
Rather than
B
Correct answer
Explanation
'In spite of' correctly introduces the contrast between hibernation's near-sleep state and the brain remaining alert. While 'instead of' and 'rather than' suggest substitution, and 'irrespective of' shows disregard, only 'in spite of' properly captures the contradiction of appearing vulnerable while actually maintaining alertness.
