Hello,
The answer is option A "mitosis".
Reason:
Mitosis one of the stages of a cell where the cells are separated into two chromosomes therefore putting them into a nucleus. Its not option B because cytokinesis is another part and divides one cell into two daughter cells (which means this is involved of the sex of the child). Its also not D because transcription is involved in gene expression.
If you need anymore help feel free to ask me!
Hope this helps!

Explanation:
Many invertebrate animals cant survive in water that has been polluted and resulted in a lowering of oxygen concentration so the presence or absence indicates the extent to which a body of water is polluted.
Lichens can be used to indicate air pollution as they grow exposed to places such us rocks and tree barks. They need to be efficient at absorbing water and nutrients to grow there. Rain water contains enough nutrients to keep them alive. Air pollutants dissolve in rain water especially sulfur dioxide can damage lichens and prevent them from growing. This makes them a natural indicator of air pollution.
