Answer:
C). Use of public hearings before congressional committees and subcommittees.
Explanation:
'Oversight' is characterized as the supervision or review of the actions by a committee in order to oversee if the proposed policy, activity, project, or plan will be successfully accomplished. One of the major examples of oversight could be 'the public hearings before the committee hearings of the congress and subcommittees' as they primarily aim to monitor, cross-check, or keep an eye on whether the required standards, laws, or regulations are adequately followed to attain the intended goals or not. Thus, option C is the correct answer.
