Destroyer Problem About Molality and Temperature Incorrect?

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.
