C Correct answer
Explanation

The great frigatebird and albatross are known to sleep while flying, using unihemispheric slow-wave sleep where one brain hemisphere sleeps while the other remains awake. They can sleep for brief periods (seconds to minutes) during long flights over oceans. This adaptation allows them to stay airborne for days or weeks without landing.
