Answer:
C) He brought its collar demonstrates nonstandard English.
Step-by-step explanation:
Every single person, be it a grammar nazi or not, will slip out and step their feet on non- standard english once in a lifetime. Some people engage themselves in nonstandard english more frequently than others.
Non standard english may be defined an an english sentence which is grammarly nor correct and requires some alterations. Also, slangs can be considered a part of non standard english. Other types of non standard english can be jargons and unrecognised words. Here "he brought its collar" is a non standard english and it is lacking a determiner before the word collar. There should be an article present in place of "its".
