D.The compilation fails at line 8.

A.m = p * (r * Math.pow(1 + r, n) / (Math.pow(1 + r, n) - 1));

B.m = p * r * Math.pow(1 + r, n) / Math.pow(1 + r, n) - 1;

C.m = p * (r * Math.pow(1 + r, n) / Math.pow(1 + r, n) - 1);

D.m = p * ((r * Math.pow(1 + r, n) / (Math.pow(1 + r, n)) - 1));

A.Replace line 1 with int sum = numbers. Stream (). Interate (0, a -> a+1. Reduce (0, (n m) -> n+m);

B.Replace line 1with int sum = number. Stream ( ) . flatMap (a -> a) .reduce (0, (n, m) -> n +m );

C.Replace line 1 with int sum = numbers. Parallel ( ). Stream ( ). Reduce (0, (n, m ) -> n + m);

D.Replace line 1with int sum = numbers. ParallelStream ( ). Reduce (0, (n, m ) -> n + m);

E.Replace line 1with int sum = number.stream. parallel ( ). Reduce (0, (n, m) -> n + m);

A.The compilation fails because there is no zero args constructor defined in class X.

B.The compilation fails because either class X or class Y needs to implement the toString() method.

C.The compilation fails because a final class cannot extend another class.

D.The compilation succeeds.
