✖ A. |
45 year |

✖ B. |
40 year |

✖ C. |
55 year |

✔ D. |
50 year |

**Solution:**

Option(**D**) is correct

Let the present age of Dennis and his father be $x$ and $y$ respectively.

and

\((x-5)=\dfrac{(y-5)}{4}\)

On solving both equation we get $y= 45$ year.

Hence, required age $=(y+5)=$ **50 year**
