The correct answer, Prince William, is the next in the line of succession following Prince Charles. This succession is dictated by the rules of primogeniture and the current constitutional framework governing the British monarchy.

As the eldest son of Prince Charles, Prince William holds a direct line of succession to the throne. The monarchy in the United Kingdom follows the lineage system, where children inherit the throne based on their birth order. This means that Prince William, being the first born, comes before his siblings, including any younger brothers or sisters.

The other options do not reflect the established line of succession. For instance, while Prince Harry is also a son of Prince Charles and stands in the succession line, he is positioned behind Prince William. Similarly, Prince Charles's youngest brother, though also part of the royal family, does not have a higher claim than Prince William. Lastly, Prince Charles does not have a daughter, so that option does not apply.

Thus, the structure of the line of succession crucially reinforces why Prince William is the rightful next in line after Prince Charles.
