A Correct answer
Explanation

Leaded glass contains lead oxide, which increases its refractive index significantly compared to ordinary glass. A higher refractive index means light bends more as it passes through the material, creating greater sparkle and brilliance. This is why lead crystal is prized for decorative glassware and chandeliers.
