Answer: c. Social learning theory
Step-by-step explanation:
KPMG in 2005 were almost indicted for their role in convincing wealthy clients to deceive the US government into believing that they had suffered losses which helped them evade taxes through tax shelters.
The marketing of these tax shelters at KPMG spread fast due to the Social learning theory where people engage in behaviour that they observed others doing.
Employees at KPMG were encouraged to be team players and so when they saw their fellow workers marketing these products to the wealthy, they too wanted to market it.
