6) From 2) and 5), the power (rate of energy flowing) at quarter
wave points will be 0

The NET power will be zero. The forward power flow vector is NOT
zero and the reflected power flow vector is NOT zero. The NET power
of zero is complete destructive interference in action. It happens
all the time to two light beams whose energies are not affected by
the interference.

7) From 6), the energy crossing quarter wave points is 0

The NET energy crossing quarter wave points is 0. The two component
energies crossing quarter wave points are not 0. They are the
constant forward power flow vector and the constant reflected
power flow vector as explained in Ramo & Whinnery. Their ratio
is the power reflection coefficient. Equation 3, page 350, _Fields_
and_Waves_in_Communications_Electronics_, Ramo, Whinnery, & Van Duzer.

(Pz-)/(Pz+)=|rho|^2

All the steps in Assertion A seem correct to me.

Yes, that is your problem. They are not correct for the two
component energies.

Can you help me find the false step which makes Assertion A false?

Here it is again, for the Nth time. There are two waves flowing in opposite
directions, each possessing its own constant energy, each flowing unopposed
end to end in the transmission line.
