Hello! I am wondering if anyone could help me with sentence patterns. The part I dont understand is when they ask to identify the pattern. An example is: Reagan's mom promised Reagan chocolate brownies.
A. S-InV
B. S-TrV-DO
C. S-TrV-IO-DO
It's pretty confusing. Thank you so so much for the help.

Wow this is confusing but I think it would be b

I think it’s b( it’s the one that looks correct)
