Answer:
A sperm cell
Explanation:
A diploid cell has 46 chromosomes which is normally signified by somatic cells. Germ cells or gametes are haploid cells therefore they contain only 23 chromosomes. Male gamete contains 22 autosomes and one sex chromosome. That sex chromosome can be X or Y.
Female gamete does not have Y chromosome as a sex chromosome, it has only X chromosome as a sex chromosome. So Y chromosome in a human cell which have 22 autosomes determines that it is a male gametic cell or a sperm cell. Sperm cells that have a Y chromosome if fuses with female gamete produce male offspring(XY).
So the correct answer is- a sperm cell.

C I believe physical pollution
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).
