What mechanism used for mobilization of transposable elements can lead to deletions in genomes?

A) Transposase sometimes deletes genomic DNA while removing DNA transposons from the genome.
B) Alignment of two transposable elements is required for mobilization and misalignment can result in deletions.
C) RNA polymerase transcribes transposable elements; when it makes mistakes, DNA nucleotides are sometimes deleted.
D) Piwi RNAs inhibit movement of transposons by deleting DNA that includes and surrounds the inverted repeats.
