What concept do sociocognitive theorists often use to explain the behavior of hypnotic subjects?

Here are the choices:

a. Expectancy

b. Altered state of consciousness

c. Divided consciousness

d. Repression

Social-cognitive theories (social influence theory - a non-state theory) argue that hypnosis is more like a role that people play (although importantly, they might not be doing it consciously/deliberately). So the answer might be b. Altered state of consciousness
