Query regarding dig output

[Gaurav Kansal]

Dear Sir,

 

When I am query through dig for nkn.in domain without any additional
parameter, It is showing 3 ADDITIONAL records.

And when I am query through dig for same nkn.in domain with +dnssec
parameter, It is showing 4 ADDITIONAL records but there are only 3 answers
in ;;ADDITIONAL SECTION.

Why is it so???????
