C

Explanation:
Let the daughter's age be $x$ and father's age be $4 x$.
So as per question, $4 x+5=3(x+5) .$ So $x=10$.
Hence present age of daughter is 10 years and present age of father is 40 years.
So after $5+5=10$ years, daughter age would be 20 years and father's age would be 50 years.
Hence father would be $50 / 20=2.5$ times of daughter's age.
