About the altimeter setting

Hey guys I have come across with one question about altimeter setting in my textbook:

Altimeter setting is the value to which the scale of the pressure altitude is set so the altimeter indicates:

A- true altitude at field elevation
B- pressure altitude at field elevation
C- pressure altitude at sea level

I wonder why A should be the answer.......I know that B and C should be wrong as pressure altitude refers to the altimeter setting when it is set to 29.92
However why A should be the answer???
Assume when a local altimeter setting is set, the altimeter should read 0, instead of the true altitude at field elevation, right?

Thanks in advance!
