Show answer and explanation

Correct answer: (C) Collection should occur in the uphill direction.

Explanation

Collection uphill imposes greater vehicle effort and is not the preferred routing rule; downhill collection is generally favoured. Thus C is the requested undesirable condition.

Avoiding repeated travel and rush-hour congestion improves efficiency. Finishing near disposal reduces the final haul. **Answer: C only**.
