C. The budget department staff is responsible for preparing the budget and for reporting on budget cost variances: This may indicate concentration of duties but is less severe than a direct conflict of interest.

D. The accounting department has one clerk prepare vendor payments and another clerk reconcile bank accounts: This demonstrates good segregation of duties, not a weakness.
