In terms of epigenetics,how the promoter would be described for a gene that is not expressed in lung tissue but is expressed in heart tissue?

A)The promoters should appear the same in both types of cells,but the mRNA produced would be hypermethylated more in lung cells compared to heart cells.
B)In lung cells,the cytosines of the promoter would be hypermethylated,and would be hypomethylated in heart cells.
C)In lung cells,the guanines in the promoter would be hypomethylated,but would be hypermethylated in heart cells.
D)In lung cells,the cytosines of the promoter would be hypomethylated,and would be hypermethylated in heart cells.
E)In lung cells,the guanines in the promoter would be hypermethylated,and would be hypomethylated in heart cells.
