Asexual, because asexual organisms always have variation within species.

|
|
Sexual, because sexual organisms have variation within species.
|
|
|
Both Asexual and Sexual reproduction would be beneficial, because they both have variation within species.
|
|
|
Asexual, because asexual organisms have no variation, so they can adapt to a changing environment.

Detailed explanation-1: -2) If the environment is stable (unchanging), and a particular organism is very well adapted to it, asexual reproduction has an advantage over sexual reproduction. If however, the environment changes (as we know it usually does), then sexual reproduction is favored since it allows for new combinations of genes.
Detailed explanation-2: -During sexual reproduction the genetic material of two individuals is combined to produce genetically diverse offspring that differ from their parents. The genetic diversity of sexually produced offspring is thought to give species a better chance of surviving in an unpredictable or changing environment.
Detailed explanation-3: -Sexual reproduction has been favored by evolution probably because the random recombination of genetic information improves the chances of producing at least some offspring that will survive in an unpredictably variable environment.
Detailed explanation-4: -Sexual reproduction produces a new combination of genes in the offspring that may better enable them to survive changes in the environment and assist in the survival of the species.
