What will be logged for console.log(Kris.age) when the Person prototype is changed?

When considering the console.log output for Kris.age after the Person prototype is changed, it is important to understand how prototype inheritance and property lookup work in JavaScript.

If Kris is an instance of the Person constructor, this instance would naturally inherit properties from the Person prototype unless those properties are defined directly on the instance. If, at some point, the age property of the Person prototype is changed, then any instance relying on that prototype for its properties will reflect this change if they do not have their own age property defined.

For example, if the Person prototype's age property was originally set to a specific value (for instance, 18) and then updated to a new value (like 29), if Kris does not have its own age property defined, then calling console.log(Kris.age) after the change will yield the updated value from the prototype, which in this case would be 29.

However, if the option selected is 18, it implies that there might be a case where Kris has its own age property set to 18 or simply pointing toward that prototype directly before any changes were made. The console output would reflect this directly on Kris, rather than the prototype's property.

In scenarios where the instance has its own 'age' property
