Kotlin val with a mutable list

What does this Kotlin code print, and would the commented-out line compile if you removed the '//'?

val items = mutableListOf(1, 2)
items.add(3)
// items = mutableListOf(4)
println(items)

A.It prints [1, 2, 3]; the commented line would not compile because items is a valB.It does not compile, because add() cannot be called on a valC.It prints [1, 2], because add() returns a new listD.It prints [1, 2, 3]; the commented line would compile because the list is mutable
