Answer 1

Looks like homework to me, but anyway…

ICollection<String> result = new List<String>();

foreach (String region in list1)
{
    foreach (String state in list2)
    {
        foreach (String lang in list3)
        {
            result.Add(String.Format("{0}/{1}/{2}", region, state, lang));
        }
    }
}

// Use result...
