Answer:
B: Not wearing a personal flotation device
Explanation:
The World Health Organization (WHO) has advised not to swim alone, or after consuming alcohol and in recognized and safe places, preferably with lifeguard patrols and safety equipment present.
WHO has advised to use personal flotation devices, especially when sailing or fishing in open water, warning that conditions can change rapidly and even experienced swimmers may find themselves in trouble. In fact, it is estimated that 85 percent of annual drowning related to navigation could be avoided using a personal flotation device.
