Intoxication.

The correct answer is intoxication.

Intoxication refers to the state in which a person's ability to function mentally or physically is impaired due to the consumption of alcoholic beverages or other substances. To answer this question, you can eliminate the options one by one by considering their definitions.

1. A hangover: While a hangover can cause discomfort and physical symptoms like headache, nausea, and fatigue, it does not necessarily impair a person's ability to function mentally or physically at the same level as intoxication.

2. A blackout: A blackout, also known as alcohol-induced amnesia, refers to a period of memory loss that occurs while someone is intoxicated. While memory loss is a characteristic of a blackout, it may or may not involve impairment in physical or mental functioning.

3. Intoxication: As mentioned earlier, intoxication is the state of impaired physical and mental function due to the consumption of alcohol or other substances. This is the correct answer.

4. A coma: A coma is a severe medical condition characterized by a prolonged period of unconsciousness, where a person is unresponsive to external stimuli. In a coma, a person is not capable of functioning mentally or physically, but it is not necessarily related to solely alcohol or substance consumption.

Therefore, the correct answer to the question is "intoxication."

The state in which a person's ability to function mentally or physically is impaired is called intoxication.
