A and C are not suitable extension method => you can only use them with IEnumerable<int> D use Take before Skip => So you will just take the "n" fisrt entries of the collection and the Skip will withdraw element of the take IEnumerable return.

For example: You want to get Page #3, your previous pages contain 10 elements: source.skip(page-1) * pageSize - that will skip the previous two pages (2 pages *10 elements = skipping 20 elements .Take(pageSize) - will take the elements needed for the third page. - the elements from 20 to 30 :)
