Step 1: Understanding the Question:
Energy Management in a household aims to prevent fatigue. Effective rest is provided not just by sitting down, but by managing the Work Load.
Step 2: Detailed Explanation:
• C. Eliminating tasks: The best way to rest is to not do unnecessary work. Using work simplification to cut out redundant steps (e.g., drip-drying clothes to avoid ironing).
• D. Delegating tasks: Sharing the burden with family members or help provides actual time off for the primary worker.
• E. Advance planning: By completing chores ahead of time, one avoids \enquote{Peak Loads} (too much work at once), which allows for planned intervals of rest.
• Exclusion: Starting early (A) just increases the total work duration. Working fast (B) increases the Physiological Cost and leads to faster exhaustion, making the rest period less effective.
Step 3: Final Answer:
Management techniques C, D, and E are valid ways to create effective rest periods.
Therefore, the correct answer is C.
