Answer:
IRONY IS WHEN SAY SOMETHING AND DO WHATEVER IS OPPOSITE TO IT.
BUT THERE IS NOTHING IRONIC IN THIS PICTURE.
OR THIS CAN ALSO BE IRONIC IN THIS PICTURE:
1. THE MAN CAN USE THAT FLOATING THING TOE SCAPE BUT HE IS NOT TRYING TO IT.
this is a hammock.
as a hammock has a rope at both the ends so it can be used to trap air inside and if has done that he can use it get to safety by letting it to float and he can sit on it and push the water backward and can reach somewhere safer. . but he is not doing it. (THIS CAN BE CONSIDERD IRONIC)
2. The man is in danger but in the picture he seems to smile. this also can be an answer. (THIS IS MORE RELAVENT THAN THE FIRST ONE)
