The c-chart is the best choice for this situation because it is used for monitoring the number of defects in a sample when the size of the sample may vary. In this case, the number of errors reported each day can vary, so the c-chart would be appropriate to track the average number of errors per day and determine if there is a significant increase in errors over time. The other charts listed (p-chart, R-chart, and 11eab475_23ab_dba1_acdb_495bf0dc3427_TB4044_11-chart) are not appropriate for this situation because they are either used for binary (yes/no) data or continuous data, which is not what is being measured here.
