Which best identifies the rhyme scheme of this stanza?

now sam mcgee was from tennessee,
where the cotton blooms and blows.
why he left his home in the south to roam
’round the pole, god only knows.
he was always cold, but the land of gold
seemed to hold him like a spell;
though he’d often say in his homely way
that he’d “sooner live in hell.”
