The lighting board makes the most sense because its controlled by the electrician. The gobos is a dark plate or screen used over the light. A ellipsodial reflector is a light control device and a frensel is a special type of lens so B makes the most sense.

The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
According to the proposition that the term music is inescapably tied to Western culture and its assumptions, the Western culture is apparently doomed to a certain measure of ethnocentrism.
When we are referring to ethnocentrism, this means that some cultures think that their culture is superior the other cultures. This is an arrogant point of view in that one group of people considered themselves better just for the simple fact that their ancestors were better or more powerful.
This of course is part of some powerful countries in the western civilization that is reflected in cultural aspects such as music.
Ethnocentrism has been the generator of many ethnic and racial conflicts in the western world.
