B)Half an hour after having the last drink.

The blood alcohol level is detected in the blood within 5 minutes, although the maximum peak of alcohol in the blood is reached between 30-90 minutes later. On average 1 hour after we have had our last drink.
This is because alcohol takes some time to travel through our body and be metabolised by the liver. After that hour, the blood alcohol level will begin to slowly decrease, requiring several hours for the total elimination of alcohol.
