I could be wrong, but D sounds a bit off to me; I don't recall data types having rows like that.

I'm not entirely sure, but I remember something about data types being related to how values are organized, maybe C?

I think a data type is more about having a named set of values, so I might lean towards A.

I’m torn between A and C. A seems right, but C makes sense too since it relates to how data is organized.
