Report a typo

You have a generic function doubleTypesTry() which takes List<T> as an argument. Select the correct form where the type T has two upper bounds — the types Type1 and Type2.

Select one option from the list

fun <Type1, Type2> doubleTypesTry(list: List<T>) { }

fun <T extends Type1 & Type2 > doubleTypesTry(list: List<T>) { }

fun <T> doubleTypesTry(list: List<T>) where T: Type1, T : Type2 { }

fun <T> doubleTypesTry(list: List<Type1, Type2>) { }
