When composite transposons are formed
A- a small deletion occurs in the transposase gene of an IS element
B- a small deletion occurs in the transposase gene of an IS element and plasmid is integrated
C- an IS element integrates with another IS element with the help of a plasmid
D- two IS elements integrate into a chromosome with only a small distance separating them
