Linkage group refers to number of type of chromosome present in species. Human have 22 autosomal linkage groups, one X and one Y linkage group. Rearrangement of chromosomal segment between two non homologous chromosomes i.e., translocation moves gene of one linkage group to that of other, which occurs due to an induced abnormality and is not part of the regular cell cycle.

Inversion and duplication cause rearrangement of genes on same chromosome.There is a change in the order of genes within the same linkage group. 

Crossing over results in exchange of genes between two homologous chromosomes. A process that occurs during Meiosis I resulting in recombination.

Therefore, the correct answer is option C.
