(D) In a cubic unit cell,$X$ atoms are present at the corners.Number of $X$ atoms per unit cell $= 8 \times \frac{1}{8} = 1$.$Y$ atoms are present at the face centers.Number of $Y$ atoms per unit cell $= 6 \times \frac{1}{2} = 3$.Therefore,the ratio of $X:Y$ is $1:3$.The formula of the compound is $XY_3$.Thus,option $(D)$ is correct.
