Answer:
b. Demonstrative
Step-by-step explanation:
Demonstrative adjectives are those that modify or give further detail of a noun by indicating or where the noun is (near or far away) or indicating which noun the speaker is referring to. We can easily identify them because they are always placed before a noun and there are only four: "This," "that," "these," and "those"
Examples of sentences containing demonstrative adjectives:
Those books over there are my sister's.
I like this movie, not that one.
These jokes will never get old.
