Answer:
D). Attitude Inoculation.
Step-by-step explanation:
'Attitude inoculation' is demonstrated as the manner or pattern in which a specific belief or attitude could be secured or protected against the exposure or influence. William J. Mcguire's proposed this theory in 1961 to elaborate that how individuals can safeguard their existing beliefs as well as attitudes from being subject to change due to various influential sources like peer-pressures, advertisement, attractions, etc.
In the given example, 'attitude inoculation' has been employed by using small contradictory arguments or examples like 'tell you..only people with problems to begin with getting into trouble with drugs' that would help protect the existing belief of considering the drugs as a dangerous thing and adopts an in-experimental towards it. Therefore, she employs 'attitude inoculation' to protect/resist her own beliefs from being changed due to various influences and persuade her to ignore any kind of experimentation with drugs. Thus, option D is the correct answer.
