根据您的要求，您可以将handleCheckboxQuestionInput更改为：

const handleCheckboxQuestionInput = (e) => {
    const answer = e.target.value;
    setSelectedAnswers((prevAnswers) => {
      if(prevAnswers.includes(answer)) {
        return prevAnswers.filter(e => e !== answer)
      } else {
        return [...prevAnswers, answer]
      }
    });
  };

并且在输入元素处改变为：

<input
    type="checkbox"
    name={currentQuestion}
    value={option}
    key={i}
    checked={selectedAnswers.includes(option)}
    onChange={(e) => handleCheckboxQuestionInput(e)}
 />

希望能帮到你
