In the given question the correct option is missing, which can be described as follows:
"It transforms binary, null variables into the groups."
Explanation:
These variables are real variables, which could also take up a series of variables, that are either constrained or defined. This can be regarded as a listing. It is used to analyze and convert it, into binary in the following ways, and wrong choices can be described as follows:
In option a, It can't combine, it only converts.
Option b and Option c is wrong because, it can't convert numeric, it only convert binary number to dummy variables.
I believe the answer is Virtual Private Network (VPN).
Know this answer is late, but im doing my deed hoping i this can help someone else pass this darn class. Best of Luck to whoever is taking the same course. You can do it if my lazy self can do it! It'll be okay ;)
