 Maybe but I don't promise that the response to the incorrect answer
will sound the same.

A c function is correctly simulated when its machine language
instructions are emulated with an x86 emulator in the order
that they are specified by the x86 machine language of this
c function.

It means that 1 to N instructions of D are correctly simulated

stuck in recursive simulation D cannot possibly reach is own
line 06 and halt.

 If you mean that H cannot simulate D to the line 06 then say so.
A D that is simulated by H is D and so is a D that is not simulated
by H so both can do what a D can do. Saying "simulated by H" adds
nothing.
 

For non-terminating functions we can only correctly
simulate N machine language instructions.

When 1 to 2^64 instructions of D are correctly simulated by H
it becomes clear that for every H/D pair of the infinite set
of H/D pairs D correctly simulated by H remains stuck in recursive
simulation.

 If you think that the meaning of "correctly simulate" is not
important you should not use those words.
 

I must use those words or a standard of incorrect simulation
is assumed. We have been going over the term "correct simulation"
in these forums with dozens of people and hundreds of messages
over several years.
CORRECT SIMULATION DEFINED
   In the above case a simulator is an x86 emulator that correctly
   emulates at least one of the x86 instructions of D in the order
   specified by the x86 instructions of D.
   This may include correctly emulating the x86 instructions of H in the
   order specified by the x86 instructions of H thus calling H(D,D) in
   recursive simulation.
