Final answer:
The word "water" best matches with the option d) 'freely', relating to the natural, unhindered flow of water. Option d is the correct answer.
Step-by-step explanation:
The word "water" can be interpreted in various contexts; however, when matched with the options provided, the best fit is d) freely. The word "freely" is used to describe something that is done without restriction or cost, which aligns well with the nature of water flowing without hindrance when it is not contained.
Conversely, the other options such as like water, lavishly, and extravagantly do not directly correspond to the essential quality of water itself.
So Option d is the correct option among the given options.
