According to clause 10.2.1.b of ISO 9001:2015, the organization should evaluate the need for action to eliminate the causes of nonconformities, in order to prevent their recurrence. This means that the organization should identify and address the root causes and contributing factors of the nonconformities, and implement appropriate corrective actions that are effective and proportional to the impact of the nonconformities. In this case, the evidence statement that supports the finding of nonconformance is C, because it shows that the organization did not take effective actions to prevent the recurrence of the spelling errors in the print run, which resulted in repeated customer rejections and dissatisfaction. The other options are not directly related to clause 10.2.1.b, although they may indicate other nonconformities or weaknesses in the organization’s QMS. For example, option A may relate to clause 7.2 on competence, option B may relate to clause 8.6 on release of products and services, and option D may relate to clause 7.1 on resources.
