Here we require actions that show that some action is being taken against the accused and that someone takes responsibility for letting the wrongdoings happen.
Response 3’s suggestion of denying all the financial irregularities will cause suspicions to rise among the employees regarding the morals of Ava and the presumed nepotism that led to Bhushan’s appointment and promotion.
Response 4 tries to avoid blame by stating the good financial performance of the company.

Responses 1(taking responsibility), 2(taking action against the accused) and 5(reason for Bhushan's appointment and promotion) are the most appropriate actions.
