It's option B.

Flexural rigidity is EI having Nm^2 units.

Snehal Wankhede said: (Sep 2, 2016)  
Option B.

Flexural rigidity = EI = Nmm2 = ML3T-2.

Sadashiva said: (Jan 14, 2017)  
EI = ML^-1T^-2xL^4.

Balia Ucp said: (Mar 14, 2017)  
Here, EI = [ML^3T ^-2].

Mahadev said: (Mar 20, 2017)  
@Snehal and @Balia is correct.

E=N/m ^2, I=m^4.
N=mass * gravity = Kg * m/sec.
= ML^3/T.

Options A correct.

Roy said: (Sep 27, 2017)  
B is the right answer.

(Kg-m/s^2)*1/m = kg/s^2 = MT^-2.
