Tax exemptions for house registration charges under sec 80c

I have few queries on tax exemptions provided for house registration charges under Section 80C.
Could you please clarify the below queries and provide detailed explanation.

1..I had booked a new flat which is under construction now. What charges paid towards registration are exempted under Section 80C.
2..Is construction agreement charges paid to the state government for flat registration qualify for tax exemption under Section 80C.
3.. Does Mortgage deed charges(MoD) paid to the registrar office exempted under Section 80C.

I went through the Section 80C of IT act 1961-2014 to see if these charges are mentioned there. 
It says "stamp duty, registration fee and other expenses for the purpose of transfer of such house property to the assessee" . Here what charges are classified as other expenses?

I'm expecting some help from all on this.
