Concept:The relation is based on a constant difference between the two numbers in each pair.Explanation:For the pair $X : 679$, the second number is obtained by subtracting $146$ from the first number.So, $X - 679 = 146$.Therefore, $X = 679 + 146$.This gives $X = 825$.For the pair $864 : Y$, the same difference must be followed.So, $864 - Y = 146$.Therefore, $Y = 864 - 146$.This gives $Y = 718$.Thus, the complete pairs are $825 : 679$ and $864 : 718$.Answer:Hence, $X = 825$ and $Y = 718$, which matches Option A.
