Correct option is C)

Firstly we have to find the factors for the above numbers

$3141 =3(3×47) $, Not a cube

$3294 =3(2×3×7×7) $ , not a cube

$3216 =3(6×6×6) $, a cube

$3496 =3(2×2×2×2×31) $, not a cube

From the above results, $216$ has the perfect cube factors.

$∴$ $216$ is the perfect cube.
