(b)

Explanation:

Rotational inertia of a cylinder of mass $M$ and radius $R$ rolling around cylinder axis or symmetry axis which passes through its center of mass is given by the expression.

${I}_{c m} = \frac{1}{2} M {R}^{2}$ ......(1)

$\implies$ For same mass of two cylinders

${I}_{c m} \propto {R}^{2}$

Implies that cylinder with larger radius will have larger rotational inertia.
