"They are my parents."
Translation:Ce sont mes parents.
'il est' and 'ils sont' are used for unmodified nouns. 'C'est' and 'ce sont' are used for modified nouns. Here, 'ce sont' is used because the noun 'parents' has been modified by saying 'mes'.

The impersonal expression "c'est" changes to "ce sont" when followed by a plural noun. In this expression, "ce" is a pronoun and it does not change to "ces" (not: ces sont).
"Ces" is an adjective (plural of ce, cet, cette), not a pronoun. You use it only when it is followed by a plural noun.
