D Correct answer
Explanation

Let Lucy's age be 5x and Mark's be 3x. Given 5x - 3x = 6, so 2x = 6, x = 3. Lucy's age = 5 * 3 = 15.

AI explanation

Let Lucy's current age be 5x and Mark's current age be 3x based on the given ratio. Because Lucy is 6 years older than Mark, the difference between their ages is 6, so 5x - 3x equals 6. This gives 2x = 6, meaning x equals 3. Lucy's current age is 5x, which is 5 multiplied by 3, resulting in 15 years.
