Answer:
1. Whose
2. Hers
3. One
Step-by-step explanation:
1. ____ bag is this?
A.) Who
B.) Whose
C.) Whom
D.) Who's
B.) Whose. "Who" wouldn't work, as it's grammatically incorrect. "Who's" is a contraction of "Who is", therefore wouldn't be right in this sentence, either. 'Whom' is an object pronoun that is used to indicate the person who received an action. 'Whose' is a possessive pronoun that is used to refer to which person something belongs to. Therefore, "Whose" is the right answer"
2. Is it...
A.) She
B.) Her
C.) Hers
C.) Hers. For this sentence, "Hers" would be the only logical response, as "Is it she?" is grammatically incorrect, as well as "It is her"
3. This shirt is too small. I need a big...
A.) one
B.) ones
C.) one's
D. the one
"One". This would be the only response that works with the context. "Ones" would be grammatically incorrect with the given sentence. "One's" is a contraction of "one is" (e.g. "No one's listening"), therefore it would not work in the sentence. "The one" wouldn't, either, as it wouldn't make sense in this sentence
So, the answers are
1. Whose
2. Hers
3. One
