Place the correct description of the compiler output on the code fragments to be at lines 4 and 5. The same compiler output may be used more than once. 1. import java.util.*; 2. public class X { 3. &emsp; public static void main(String[] args) { 4. &emsp;&emsp; /* insert code here*/ 5. &emsp;&emsp; /* insert code here*/ 6. &emsp; } 7. &emsp; public static void foo(List list) { 8. &emsp; } } Code Compiler Output a. ArrayList x1 = new ArrayList (); foo(x1); (i) Compilation succeeds b. ArrayList x2 = new ArrayList (); foo(x2); (ii) Compilation fails due to an error in the first statement c. ArrayList x3 = new ArrayList (); foo(x3); (iii) Compilation of the first statement succeeds but compilation fails due to an error in the second statement d. ArrayList x4 = new ArrayList(); foo(x4);
