Should Specific Wieght of incompressible fluid only be taken at STP?

1.	Should Specific Wieght of incompressible fluid only be taken at STP?
A.	Yes, as specific weight may show large variation with temperature and pressure
B.	No, it can be taken for any temperature and pressure
C.	It should be taken at standard temperature but pressure may be any value
D.	It should be taken at standard pressure but temperature may be any value
