Answer:
The correct answer is option - binary fission.
Explanation:
The conjugation process is a process in which two bacterial cells come in direct touch with pilus and fuse to transfer its genetic material or share genotype from donor to recipient cell. It is equivalent to sexual reproduction ( fertilization) or mating.
On the other hand, binary fission one cell body divides into two cells by replication of its genetic material. Each cell contains one copy of the genetic material. It is an asexual reproduction which is directly opposite to conjugation.
Thus, the correct answer is option - binary fission.
