Melissa is writing a class called Cell. Which method has she set up to return a double? public class Cell
{
private int chromosomes, rna;
public double time, h2o;
private static int cellCount = 0;
private static double mCount = 4.0;

public Cell()
{
chromosomes = 23;
rna = 1;
h20 = 2.0;

cellCount++;
System. out. println(“There are now ” + cellCount + “ cells”);
}

A. public Cell(int a_chromosomes, int a_rna, double a_h20)
{
chromosomes = a_chromosomes;
rna = a_rna;
h20 = a_h20;
}

B. public int getChromosomes()
{
if (chromosomes < 1) {
throw new IllegalArgumentException(“chromosom es is less than 1”);
}
return chromosomes;
}

C. public double get_mCount()
{
return mCount;
}
