In UUIDs, the 13th digit represents the version number, and for UUIDv1 and UUIDv2, it is always 1 and 2, respectively. For UUIDv4, the 13th digit is always "4". Therefore, to calculate the variance of a UUID, we need to change the 13th digit to "4" and then calculate the variance. Option C is the only one with "d" as the 13th digit, which can be changed to "4". The other options have different digits as the 13th digit, so they cannot be correct.
