Please do explain me table 5.3 of ncert regarding genes and chromosomes and whether it is true for all the conditions of gene and chromosome

Answer is Column A -Gene and Chromosome both Coloumn B -Chromosome.

It is because the 3^rd statement in coloumn A talks about independent pair.The word independent has to be used for genes only as Chromosomes are always independent but genes when shows Linkage aren't independent.So coloumn A holds good for both Gene and Chromosome but when it comes to coloumn B only Chromosome is possible.One gene need not be separated from other independently when they are linked on same chromosome.

Hope this is helpful.

Because of similarity in pairing and inheritance of gene and chromosome are quite same but the one pair of  chromosome independent to the other pair of chromosome while in case of Gene  one pair is only independent to the another one pair not by all pairs so the A is for chromosome and B for gene.
