Pension Form 10 D Help In Filling Form

Can someone please explain point 10, alternative 1 regarding the 90% quantum of pension and return of capital. My father is 65, retired. Thanks for your help

After the introduction of the EPS in 1995, the commutation of pension and return of capital were implemented for few years. If this was opted, a pensioner would get 90% of his eligible pension and after his death his widow would be paid a lump sum amount and would also get further reduced pension during her life time. You can refer to the EPFO website for full details of the scheme.
