Answer: c

On 21 August, Netherlands' Van der Weed won the men's 10km open water swim. This is the first time that the so-called water marathon has become an official Olympic event, and the first Olympic champion born in this event is also legendary.

If you look closely at Van der Wade's head, you'll see two shocking scars. The two coin-sized scars are not unusual decorations, they are the marks of chemotherapy and bone marrow transplants for leukemia patients, such scars that vibrate when a person speaks or even gasps. The 27-year-old Van der Wade is a talented swimmer, but at the age of 20, he was diagnosed with leukemia, which may have claimed not only his athletic career, but also his life.

Luckily, Van der Wade was able to win the battle against the disease, and after a successful bone marrow stem cell transplant, Van der Wade was back on the field. In 2008, he wrote the most heroic stroke of his sports career in Beijing, and "gold inlaid jade" is the best reward for a hero like him.
