The code segment below is intended to calculate the circumference c of a circle with the diameter d of 1.5. the circumference of a circle is equal to its diameter times pi. /* missing declarations */c = pi * d; which of the following variable declarations are most appropriate to replace /* missing declarations */ in this code segment? a) int pi = 3.14159; int d = 1.5; final int c; b) final int pi = 3.14159; int d = 1.5; int c; c) final double pi = 3.14159; double d = 1.5; double c; d) double pi = 3.14159; double d = 1.5; final double c = 0.0; e) final double pi = 3.14159; final double d = 1.5; final double c = 0.0;
