Which situation describes being "drunk" in legal terms?

In legal terms, being "drunk" typically refers to the consumption of alcohol that leads to impairment. This state of impairment can affect a person's motor skills, judgment, and overall ability to function normally. Laws regarding intoxication often hinge on observable impairment rather than just the presence of alcohol in one's system, which is why option A accurately reflects the legal definition of being drunk.

From a legal perspective, it is not sufficient to merely have alcohol in the body; it is the impairment in one’s ability to perform tasks or react appropriately that constitutes being drunk. Thus, judges and law enforcement typically assess individuals based on their observable behaviors and performance in activities such as driving, rather than just their blood alcohol content (BAC) alone.

The other options do not capture the essence of being "drunk" in legal language. Simply having the presence of alcohol without signs of intoxication does not equate to being legally drunk. Alcohol consumption in a controlled environment or with a sober companion also doesn’t imply impairment, as it is entirely possible for individuals to drink responsibly without exhibiting any signs of being impaired.
