Organisms with big genomes have large number of sequences that resemble DNA (Deoxyribo Nucleic acid) transposons, whereas organisms with small genomes have fewer such sequences.
Hence, the correct answer is option (c)
• Though maize has more genes than rice, the comparatively larger size of maize genome is not due to the number of genes. Hence, option (a) is not correct
• Rice has fewer genes than maize. Hence, option (b) is not correct
• Retro transposons are mostly present in animal chromosomes. Hence, option (d) is not correct
