English grammar worksheet focusing on plural forms and noun usage.

Let me work through each question step by step.

Question 12 (partial - showing options): A. mother, B. friend, C. grandparents, D. sister
This appears to be a "find the odd one out" or similar question. Looking at the pattern of other questions about plural forms, this might be asking which word is already plural. "Grandparents" is plural while the others are singular. But without the full question stem, I'll note: C. grandparents (plural form)
