Final answer:
The triple bottom line consists of people, planet, and profit, reflecting a company's social, environmental, and economic impacts, respectively. Since none of the provided options match these concepts, 'd. None of these' is the correct choice.
Step-by-step explanation:
The concepts that are part of the triple bottom line are people, planet, and profit. This approach to business emphasizes the importance of not just financial results but also the social and environmental impacts of a company’s operations. Within this framework, 'people' relates to fair and beneficial business practices towards labor and the community where a business operates. 'Planet' reflects the company's environmental responsibility efforts, such as reducing carbon footprint and sustainable resource use. Lastly, 'profit' indicates the economic value created by the company. Hence, none of the given options directly corresponds to the triple bottom line concepts. However, if one must choose from the provided options, 'd. None of these' would be the most accurate answer since the correct concepts are not listed among the options provided.
