doubt SC A

At issue in the proceeding is whether the gaming firm can verify that the site’s users are

1) over 21 and
2) in a legal gambling state or country,
3) using special identification and location software, among other tools.


At issue in the proceeding is whether the gaming firm can verify that the site’s users are ................ using special identification and location software, among other tools.


If you look at the meaning then "using special identification and location software" is modifying "USERS".


What you are saying is :

"the gaming firm can verify.....using special identification and location software, among other tools. "

but that is not the INTENDED MEANING of the original sentence.


is OA: A ?


b) IS WRONG

At issue in the proceeding is whether the gaming firm can, with the use of special identification and location software,


Usage of with is WRONG


c) Same as B

d) verify that the site’s users are over 21 and a legal gambling state or country, with the use of special identification and location software, among other tools.


Bolded part looks awkward

e) can verify that the site’s users are over 21 and in a legal gambling state or country, among other tools


site's users are among tools??

thanks

Generally, COMMA + VERBing serves to refer to the NEAREST preceding subject.
OA: At issue in the proceeding is whether the gaming firm can verify that the site’s users are over 21 and in a legal gambling state or country, using special identification and location software, among other tools.
Here, using seems to refer to users -- the nearest preceding subject -- implying that the USERS are USING special identification and location software.
Not the intended meaning -- sufficient reason to eliminate this answer choice.

I would ignore this SC.
The OA is not viable.
