Destroyer Problem About Molality and Temperature Incorrect?

[Stacker]

Which statement is false?

a) Critical pressure is that pressure when solid, liquid, and gas all are in equilibrium.
b) Critical pressure is the end of the liquid-vapor equilibrium line on a phase diagram.
c) Molality is temperature dependent
d) An alloy is a solid solution of two or mole metals.
e) A and C

Destroyer lists the answer as A. But isn't choice c false as well making the actual correct answer E? I thought molarity (mol/L) was temperature dependent but molality (moles/kg) is independent of temperature.

You probably have an old edition of the book, it's correct in 2012 Destroyer.

I think the answer is E also. Molarity depends on volume, which is dependent on temperature. Molality is temperature independent since it is dependent on mass. A is definitely false.
