accessing array in array items

How can I access an array item in another array?
How can access ["AC1", "AC2"],["BC1", "BC2"], and ["DD1", "DD2"] from the ListOfColumns array below?

<script type="text/javascript">
	var ListOfColumns = [["AA", "AB", ["AC1", "AC2"], "AD AE"], ["BB", "BB", ["BC1", "BC2"], "BD BE"], ["CA", "CB", "CC"], ["DD", "DE", ["DD1", "DD2"]]];
	console.log("[0]: "+ListOfColumns[0]);
	console.log("[0][0]: "+ListOfColumns[0][0]);
	console.log("[0][1]: "+ListOfColumns[0][1]);
	console.log("[0][2]: "+ListOfColumns[0][2]);
	console.log("[0][3]: "+ListOfColumns[0][3]);
	console.log("[1]: "+ListOfColumns[1]);
	console.log("[1][0]: "+ListOfColumns[1][0]);
	console.log("[1][1]: "+ListOfColumns[1][1]);
	console.log("[1][2]: "+ListOfColumns[1][2]);
	console.log("[1][3]: "+ListOfColumns[1][3]);
	console.log("[2]: "+ListOfColumns[2]);
	console.log("[3]: "+ListOfColumns[3]);

I was able to do that.
I think I explained it wrong.

How do I access just "AC1", "BC1" or "DD1"?
var ac1 = ListOfColumns[0][2][0];
var bc1 = ListOfColumns[1][2][0];
var dd1 = ListOfColumns[3][2][0];
