Simplify the following statements. Here, b is a variable of type boolean and n is a variable of type int.

a. if (n == 0) { b = true; } else { b = false; }

b. if (n == 0) { b = false; } else { b = true; }

c. b = false; if (n > 1) { if (n < 2) { b = true; } }

d. if (n < 1) { b = true; } else { b = n > 2; }
