Question

1. I'd like you to meet my family.

This is my dad, mom and little brother.

2. I'd like you to meet my family.
These are my dad, mom and little brother.
-----------------------------------
Do we have to use 'This is' or 'These are' in this case?

Answer 1

Either one is understandable, but the second set is grammatically correct since you're introducing three people, not just one.
