Explanation:

Folsom Prison Blues is a song by Johnny Cash. The lyrics are given below:

I hear the train a comin'

It's rolling round the bend

And I ain't seen the sunshine since I don't know when

I'm stuck in Folsom prison, and time keeps draggin' on

But that train keeps a rollin' on down to San Antone

When I was just a baby, my mama told me

"Son, always be a good boy, don't ever play with guns"

But I shot a man in Reno just to watch him die

When I hear that whistle blowin', I hang my head and cry

I bet there's rich folks eating in a fancy dining car

They're probably drinkin' coffee and smoking big cigars

Well I know I had it coming

I know I can't be free

But those people keep on movin'

And that's what tortures me

Well if they freed me from this prison

If that railroad train was mine

I bet I'd move it on a little farther down the line

Far from Folsom prison, that's where I want to stay

And I'd let that lonesome whistle blow my blues away

i think the answer is either c or d

im thinking d might make more sense though

sorry if im wrong
