Scientists cannot directly observe dark matter, but they know it exists by C, the way it exerts a gravitational pull on other matter. Most of the cosmic entities like galaxies do not have enough observable matter within them to logically exist, i.e. the amount of matter they have can’t hold the galaxy together. These large bodies that can’t exist by the laws of nature somehow do, and thus the concept of dark matter and energy supports both the concept, and the galaxy itself, in a sort of way (humor intended). :)

Deletion is when a part of the chromosome is deleted. (Removed)
Insertion is when part of our chromosome has an extra bit added to it.
Translocation Is when one part of the chromosome is moved to another chromosome.
The correct answer is inversion, to invert means to turn upside down. So when part of the chromosome is taken off but attached backwards (turned upside down) we call it inversion
Hope that makes sense
