Explanation:

- Chapel Vs Cooper: This case involved a dispute over services rendered but did not explicitly address the purchase of non-necessary items by minors.

- Balfour Vs Balfour: This widely discussed case revolved around the contractual obligations between a husband and wife and did not involve minors or their purchases.

- Nash Vs Inman: This case is famous for examining whether items purchased by a minor were considered 'necessaries.' Inman, a minor, bought extravagant items, including waistcoats, and the court found they weren't necessary as he already had an ample supply.

- None of these: This option could be considered if none of the above cases were relevant, but in this scenario, one case directly addresses the issue.

Correct Answer: Nash Vs Inman
