Common in “simple” living things
A
asexual
B
sexual
C
both
Explanation: 

Detailed explanation-1: -Animals that reproduce asexually include planarians, many annelid worms including polychaetes and some oligochaetes, turbellarians and sea stars. Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation, such as gemmae in liverworts.

Detailed explanation-2: -Characteristics of Asexual Reproduction Single parent involved. No fertilization or gamete formation takes place. This process of reproduction occurs in a very short time. The organisms multiply and grow rapidly.

Detailed explanation-3: -Asexual reproduction requires only one parent organism and results in genetically identical offspring (like a clone). Since there is no mixing of genetic information required and organisms don’t need to spend time finding a mate, populations can increase rapidly due to asexual reproduction.

Detailed explanation-4: -Common forms of asexual reproduction include: budding, gemmules, fragmentation, regeneration, binary fission, and parthenogenesis.
