Answer:
They are both right.
Explanation:
the upper thigh is proximal to the hip when compared to the knee -- this means that the upper thigh is located in a manner that it is nearer to the centre of the body or attachment, in this case, hip. It's the same for hip and knee, they are located in a certain way that their distance is the same. Upper thigh is inferior to the hip -- it is inferior to the hip because it's down from the hip. For example, rib would be superior to the hip, because it's higher compared to it.
