Can you answer this
Solution:
A variable number tandem repeat (or VNTR) is a location in a genome where a short nucleotide sequence is organized as a tandem repeat. These can be found on many chromosomes and often show variations in length between individuals. 'Variable Number Tandem Repeats' is a kind of genetic marker. VNTR are greatly variable between people, as the number of tandem repeats change often (mostly due to a replication error called replication slippage). Researchers analyse the number of tandem repeats in ones DNA to identify them, as everyone is unique.
Hence the correct option is option A
