Solution

The correct option is D Upto 10 times that of exon
In general, the intron-exon structure of eukaryotic genes is complicated, the amount of DNA in intron sequences usually exceeding that in the exons. On average, introns constitute about 10 times more DNA than exons in the genes of higher eukaryotes.
So, the correct answer is 'Upto 10 times that of exon.'
