D

Read reg 643.1 The tests of regs 643.2 to 643.6 shall be carried out in order
Therefore B A and C in that order are within that range
D is reg 643,7,3 therefore out that range

Perfect thank you very much. I’ve had my head in the regs for too long and couldn’t see what was right in front of me

Why do you ask?

Isn't it 'D' only where EFLI refers to Ze.?

You're always referring to Ze, therefore it must apply.
