Which is the correct sentence?

Re: Which is the correct sentence?
a. Peter introduced me to his roommates, who are from California.

Correct. Best.

b. Peter, whose roommates are from California, introduced me to them.

Grammatically OK, but clumsy.

c. Peter introduced me to his roommates that are from California.

Definitely incorrect. (Use of "that" in connection with people.)

Re: Which is the correct sentence?


I thought 'that' could be used for people as well as animals and non-living things.

I daresay using "that" is allowed by the "rules", but -- maybe it's different in US or "international" English -- where I come from, (Great Britain) nobody would say "My friend that is French", they'd say "My friend who is French".

This is what I found:

Sentence #c, I have heard similar sentences spoken where either "that" or "who" was used.

Thanks, TTH.

I agree with contrex. If you're looking for usage--what people say--then avoid "that" when you're referring to people.

I agree with Roberta and contrex ... "who" is almost always used for people, and "that" for inanimate objects...
