Hey there!
Here is your answer:
The proper answer to this question is option A "true".
Reason:
It is true that standard English is more limited than that if nonstandard English! Standard would have more prefixes, and suffixes or root words, but nonstandard would have the irregular words.
Therefore the answer is option A.
If you need anymore help feel free to ask me!
