Which Kotlin collection function is used to create a new collection containing only the elements that satisfy a given condition?

The correct option is filter().

In Kotlin, the filter() function is used to create a new collection containing only the elements from the original collection that satisfy a given predicate (a boolean-valued function or condition).

• sort() is used to sort the elements of a collection.
• map() is used to transform each element of a collection into a new form.
• reduce() is used to combine all elements of a collection into a single result.

The final answer is $\text{filter()}$
