Correct option is C
The tools of executive control over administration include (A) Civil Service Code, which provides guidelines for civil servants' conduct; (B) Staff agencies, which assist in policy formulation and ensure that executive directives are followed; (C) Budget, a critical instrument through which the executive controls the activities of various departments by allocating funds; and (D) Ordinances, which are executive orders that have the force of law, used to direct administrative action. E (suits against public officials) is not typically considered a tool of executive control over administration, as it is more related to judicial oversight or legal accountability mechanisms rather than executive control measures.
