A protozoan that divides to form two daughter cells just like itself would be undergoing binary fission.

Binary fission is a type of asexual reproduction which usually occurs in some single-celled organisms (protozoan) such as amoeba, and in prokaryotes such as bacteria. In the process of binary fission, DNA replication, and segregation takes place at the same time. The genetic material (DNA) of an organism is duplicated, and it then divides into two parts (forming two genetically identical daughter cells), and each new organism receives one copy of DNA.

the answer is d. none of the above

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
