Force required to accelerate a cylindrical body which rolls without slipping on a horizontal plane (mass of cylindrical body is \(m\), radius of the cylindrical surface in contact with plane is \(r\), radius of gyration of body is \(\mathrm{k}\) and acceleration of the body is

a) is

(a) \(m\left(k^{2} / r^{2}+1\right) \cdot a\)

(b) \(\left(m k^{2} / r^{2}\right) \cdot a\)

(c) \(m k^{2} \cdot a\)

(d) \(\left(m k^{2} / r+1\right) \cdot a\).
