From what I understand, 4c is not an actual hair type but a SUGGESSTED hairtype. 3c is also a suggested type from what I recall but its highly popular because of it encompasses so many "in-between" curlies
I think that 4c would look almost identical to 4b except that the curls would be so tight, there would be seemingly no definition.
But that's just my opinion
4A (some 3C-ish in front)
Thick, coarse, & UTTERLY unruly
