Answer:
a. Rao indorses his payroll check in blank.
Explanation:
There are many types of indorsements, and out of them one is "Trust Indorsement"
Trust Indorsement is an indorsement to a person who can use the funds for the benefit of the indorser.
Example:
Brian indorses a check to his employee Denny  "Payable to Denny, as agent for Brian", This is an example of trust indorsment.
Option b and c are clearly examples of trust indorsements in which you can notice that Rao has indorsed his lawyer and accountant "as agent for Rao". 
Whereas, option a is NOT a trust indorsment but rather a "Blank Indorsement"
Blank Indorsment is an indorsement that doesn't have any particular indorsee and only has a signature on it.

When real GDP produces natural output, that is, the output level is in line with the equilibrium of the labour market when the real price level is equal to the expected price level. Then the economy makes the most of its productivity, including fully utilized labour, which means that the economy is at the natural rate of unemployment.
