Answer:
            The correct option is d (diploid chromosome). 
Reason:
            In the karyotype you see that all chromosome pair upto 22 are same but pair number 23rd have different shapes. so the term homozygous, heterozygous and homologous can not be applied.

Answer:

B  homologous chromosomes

Explanation:

The each numbered group in human karyotype is known as homologous chromosome. In the homologous pair, one chromosome is derived from father while another one is derived from mother. Like in this given karyotype, there are 23 homologous pairs and in each pair one was carried by sperm while another one was carried by ovum, once they fused during fertilization they paired up. Homologous chromosome pairs contain alleles of same gene located at same loci in both the chromosomes.
