Which detail best provides an example to illustrate the central idea that follows?

The Utopians value money less than other, more useful

things.

"they have no use for money among themselves"

"they value it no farther than it deserves—that is, in

proportion to its use"

"they must prefer iron either to gold or silver, for

men can no more live without iron than without fire

or water

This question is missing the excerpt. I've found it online. It is the following:

. . . since they have no use for money among themselves, but keep it as a provision against events which seldom happen, and between which there are generally long intervening intervals, they value it no farther than it deserves—that is, in proportion to its use. So that it is plain they must prefer iron either to gold or silver, for men can no more live without iron than without fire or water; but Nature has marked out no use for the other metals so essential as not easily to be dispensed with. –Utopia, Thomas More

Which detail best provides an example to illustrate the  central idea that follows?

The Utopians value money less than other, more useful  things.

"they have no use for money among themselves"

"they value it no farther than it deserves—that is, in proportion to its use"

"they must prefer iron either to gold or silver, for  men can no more live without iron than without fire  or water"

The detail that best provides an example to illustrate the central idea is:

"they must prefer iron either to gold or silver, for  men can no more live without iron than without fire  or water"

Explanation:

All options are directly related to the central idea that Utopians value money less than other, more useful things. However, we are looking for a detail to illustrate the idea, that is, to give an example that will help readers understand or visualize it. In that case, the last option is the best one: "they must prefer iron either to gold or silver, for  men can no more live without iron than without fire  or water." From this detail, we can understand what type of thing is more valuable to Utopians than money. Something as useful as iron is certainly seen as more precious. The author even compares it to water and fire, two things we are completely dependent on to survive.
