Which transformation effectively uses "attributed" for "His success is due to hard work"?

The correct transformation uses "attributed" in a way that maintains the original meaning of the sentence. The phrase "His success is due to hard work" indicates that hard work is the reason for his success, and "attributed to" serves a similar purpose, implying a cause-and-effect relationship.

In the chosen transformation, saying "His success is attributed to hard work" conveys that hard work is recognized as the reason for his success, aligning perfectly with the original statement. This maintains the integrity of the message while appropriately incorporating the word "attributed."

The other choices introduce different nuances or subjects that shift the original intent. Some options replace "hard work" with "dedication," altering the focus of the sentence, while others phrase it differently with "based on," which can imply other types of foundation beyond the direct cause indicated by "due to." Thus, option C stands out as the most accurate transformation reflecting the original meaning.
