1, 5, 6 and 8 are correct.
2, 3, 4 and 7 are incorrect.
I don't think 3 corresponds to anything in column b. There's one answer that's close, but not exact.

7. is G?
binary is Basic unit of information
2. is A?
3. Multyply by 4 ---> shift left 1 i found this in the book after a lot of reading

almost right!
using eax as an example:
shl eax, 1 = * 2
shl eax, 2 = * 4
shl eax, 3 = * 8
shl eax, 4 = * 16
so if you say
mov eax, 10
then the results from above would be
shl eax, 1 = 10 * 2 = 20
shl eax, 2 = 10 * 4 = 40
shl eax, 3 = 10 * 8 = 80
shl eax, 4 = 10 * 16 = 160

Yea I guess... which I think is a bit weird.
I'd say a bit (Binary digit) is the basic unit of information, but not just 'binary'.
2. is A?
Yes, if I'm not mistaken, HLA is a frontend for MASM, Microsoft's Macro Assembler.
And MASM is invoked with ml.exe (MASM and LINK, just like their compiler is cl: Compile and Link. They both invoke link.exe unless you specifically tell them to skip the linking stage).
3. Multyply by 4 ---> shift left 1 i found this in the book after a lot of reading
Well, if you do shift left by 1 twice, you'd multiply by 4.
Shift left 1 is multiply by 2. So x*2*2 = x*4.
(Some CPUs can only shift by one bit at a time, so it's not that strange when one thinks "I need to multiply by 4", and then associates that with "I need to shift left by 1... two times").
