When to use the verb form "is" and "are"
The basic rule indicates that if the noun is singular, the verb form to be used is "is". If it is plural, then "are" applied.
With regards to the question above, there is the case of Is and Are with respect to the collective nouns. "Parent" is a singular noun form while "Parents" is a plural noun form.
So the twist is further reduced by the fact that the sentence starts with "One of" in indicating that the subject of the action word is singular. Hence "is" becomes the correct verb form to use.
