Question

Fill in the blanks with the most appropriate words.
_____ talking to _____ sister?

• A. Whose / yours
• B. Who's / your
• C. Whose / your
• D. Who's / yours

Answer 1

Answer: (B)

Who's / your

The correct answer is Option B.

WHO'S is the contraction of WHO IS. It is used in the present tense.

The given sentence is in the present tense.

YOUR is a possessive adjective. It describes a noun. In the given sentence, it describes and tells us more about the sister.

Thus Option B is the correct answer.

The remaining options are incorrect because:

WHOSE is used to ask about possession.

YOURS is used to refer to thing or things belonging or associated with the person the speaker is addressing.
