regarding section D
Scheme Preference is the Pension fund schemes option chosen by the subscriber for investing the pension contribution amount. At present, there is only one default scheme for Tier I.
The contribution of all the Subscribers will be invested in this default scheme. In the default scheme, the contribution is allocated to three PFMs, viz. SBI Pension Funds Private Limited, UTI Retirement Solutions Limited and LIC Pension Fund Limited in a predefined proportion and each of the PFMs will invest the funds in the proportion of 85% in fixed income instruments and 15% in equity and equity related instruments.

in my understanding there is no need to fill the scheme detail as it is default for government employess in tier I account.
we all have tier I account.
