My query is from Inheritance and Variation Principles topic in division Principles of Inheritance and Variation of Biology – Class 12

Answer 1

Right choice is (d) Shifting of a part of a chromosome to another non-homologous chromosome

For explanation: Translocation is the shifting of a part of a chromosome to another non-homologous chromosome. It results in the formation of new recombinant chromosomes as this induces faulty pairing of chromosomes during meiosis.
