The correct option is:

Nullable and non-nullable type declarations

Kotlin's type system distinguishes between references that can hold null (nullable types, denoted by ? after the type, e.g., String?) and references that cannot (non-nullable types, e.g., String). This feature forces developers to explicitly handle potential null values at compile time, significantly reducing the occurrence of null pointer exceptions.
