The correct option is A Asexual reproduction - Bacteria, Humans
Sexual reproduction generally occurs in multicellular organisms like sparrows, tortoise and humans. It involves 2 parents i.e. male and female parent. Both produce their respective gametes which fuse to form the zygote. The zygote gives rise to a new offspring.
Asexual reproduction involves only one parent. There are many ways in which organisms reproduce asexually. For example, spore production, fragmentation, budding etc. Bacteria undergo binary fission during which the parent cell splits into 2 daughter cells.
