About section while filling itr4

When I start to file tax using itr4, there is one section called 119/2(b)/92cd. Can anyone explain me what is this section is all about.

Sec 119 is Instructions to subordinate authorities where if you are filing after due date but after getting approval from board. This will hardly applicable to you. And Sec 92 cd is Advance Pricing Agreement .

Both the section are used only in exceptions.
