JAVA Code:

Which method below is functionally equivalent to the method foo()?

public static int foo(int n) { if (n<=0 || n%2 == 0) { return 0; } else { return n + foo(n-2); } } public static int bar(int n) { if (n<=0 || n%2 == 0) { return 0; } else { int a = 0; for (int i=1; i<=n; i++) { a = a + i; } return a; } } public static int baz(int n) { if (n<=0 || n%2 == 0) { return 0; } else { int a = 0; for (int i=1; i<=n; i=i+2) { a = a + i; } return a; } } public static int qux(int n) { if (n<0 || n%2 == 0) { return n; } else { int a = 0; for (int i=1; i 
Choices:
 
A. bar()
 
B. baz()
 
C. qux()
 
D. none of those methods is equivalent to foo()
