Difficulty: Easy
Correct Answer: voluntarily offered to render additional services in lieu of nothing
Explanation:
Given data
Concept/Approach
Actions that raise costs (paid leave, welfare schemes, 'lucrative' overtime) typically reduce profit unless offset by large gains. Offering additional services for free directly lowers cost per output, improving profit.
Option analysis
D (despite clumsy phrasing) implies unpaid extra work, aiding profit. E sacrifices quality (harmful long-term). A/B/C increase costs.
Final Answer
voluntarily offered to render additional services in lieu of nothing
