I am going to go with either C or D. I would side mostly with C.

The correct answer should be low to moderate intensity and long duration. For weight loss, it's better to do something at a lower intensity but for a long time than to do something quickly but pushing yourself. That's why cardio exercises and running is great for losing weight. It helps you work at your own pace and you can do them for a long time.
