Answer: Cover your head and body.
Explanation:
The recommendations are (translated to English):
"Take care of your body with wite clothes when you go out to the beach. Cover your head with a hat. Drink water"
So the option that is correct is:
Cover your head and body.
You can see that the "drink water" part is missing, but it is the only option that only has recommended actions, while all the other options have at least one action that is not in the recommended list.
