The correct answer is A. A celebrity role model who speaks out against drugs
Explanation:
A lack of self-confidence such as the one displayed by Maya makes individuals believe they cannot make decisions by themselves but need to rely on others. Due to this, individuals that lack self-confidence copy others' behaviors rather than making decisions by themselves. This can be negative in some cases, for example, if the friends of Maya use drugs she is likely to join this behavior. However, in the case Maya sees a celebrity she admires speaking against drugs, it is likely she opposes the use of drugs as well, and therefore this would be a positive influence. According to this, a positive influence that could help Maya to avoid the drugs is "A celebrity role model who speaks out against drugs".
