The correct answer should be C) bias
If the person works for a national energy company there is high chance that the person would be a bit biased towards installing the new systems. This should definitely be checked.
I think that it would be fragment but I am not sure.
I know it's not B, because arrogance is basically like pride or self-absorption, so that's false.
Apprehension, or C, is also false. The meaning of apprehension is basically anxiety or tension, so that is also false.
D is also not correct because donor is someone who gives something away to another person. Though donor is usually associated with giving away organs to help other people, it can be other things.
But a recipient is someone who receives something, such as a "Best Student" award!
A is the correct answer! :)
