Extract first item from enumerable <list customers>-CodePudding

I am new to LINQ/C#. I have an enumerable list:

System.Collections.Generic.IEnumerable<System.Collections.Generic.List>

I would like to extract the first item from each list and place that in a new list:

System.Collections.Generic.List

For example

List<customers> = from myEnumerable
                  select item[0];

What would be the correct way to form the linq query to extract element 0 from each list in the enumerable?

Thank You

IEnumerable<List<T>> input = ...;
var result = input.Select(l => l[0]).ToList();
