Let's assume Lacy's age to be x. So, Jack's age is 2x. After two years, the sum of their ages will be 73. So, (2x+2)+(x+2)=73. Solving the equation, we get x=21. So, Lacy is 21 years old and Jack is 42 years old. Therefore, the correct answer is option D - Jack is 46 and Lacy is 23, which is twice Lacy's age.
