B. An aqueous solution is in its standard state at a concentration of 1.00 M.
C. A solid is in its standard state when the atmospheric pressure is 1.00 atm and the temperature is 25C .
D. A pure liquid is in its standard state at 25C and a vapor pressure of 1.00 atm.

Look up standard states and check statement D. I don't believe the vapor pressure MUST be 1.00 atm.
C is true, apparently, contrary to what i was told...

anyways, do not choose c as your answer.
