31. 參考下面 JAVA 片段程式碼，選項中的方法何者放在 class B 不會產生編譯錯誤
(A)public int getQuotient (int i) throws ArithmeticException{return 20/i；}
(B)public double getQuotient (double d1, double d2) throws ArithmeticException{return d1/d2；}
(C)public int get (int i, int j) throws RuntimeException {return i/j；}
(D)public int getQuotient (int d1, int d2) {return d1/d2；}
