Answer:
Option (A), (C) and (D).
Explanation:
Introns are the non coding nucleotide sequence of the gene. They may present within the gene or may lie outside the exons. Introns are responsible for the gene evolution.
Introns can also responsible for encoding the proteins subunit. Introns needs to be removed from the exons by the process known as splicing. Different splicing are alternate splice, group I and II intron. Different multiple introns can be present in the gene.
Thus, the correct option is (A), (C) and (D).
