The correct option is D Do / your
The correct answer is Option D.
As a rule, YOU is followed by DO. YOUR is used when there is a meaning of belonging.
Hence DO/YOUR is the correct answer.
The remaining options are incorrect because:
Option A: OUR is a plural pronoun. There is only 1 person on this sentence.
Option B: DOES is used with plural words.
Option C: MY is used when referring to first person. YOU is in the second person.
