Wait, is it really 20 characters long? That seems odd.

I’m leaning towards option B since 32 bytes seems common for modern systems, but I could be mixing it up with something else.

I feel like I saw a similar question about data types and their sizes in our practice tests. Could it be option A or D?

I remember something about addresses being related to memory size, but I can't recall if it's a fixed length like 20 characters.

I think addresses are usually represented in hexadecimal, but I'm not sure if it's 20 bytes or 32 bytes.
