Answer:
Comparative
Step-by-step explanation:
Comparative is a word when combining two adjectives, in this instance, larger is our word given.
Since it is comparing two things, you can say as in the example:
This book is LARGER than the teddy bear.
My leg is LARGER than a mouse.
WOW! Your ruler is LARGER than mine!
Let's look at the other examples,
Reflexive would not fit because larger does not talk about a clause by which it is used.
Demonstrative would also not fit as it refers more to an emotional feeling
Superlative would not work as it talks about comparing more than two things
Cooperative would not work as it talks about helping others.
I Hope This Helped :D
