Is it true or false that a natural selection acts on phenotypes not genotypes?

It doesn't. Phenotypes are viable or not in a given environment, and this influences whether the corresponding genotypes get passed on. Selection works on genotypes via the effects of their expression, their phenotype.
The answer you may be looking for is that phenotypes maladapted to their environment have less babies, and pass on less copies of their genes. "Natural selection" is the whole process over generations. "Selection" may refer to misadapted bodies/phenotypes reproducing less due to illness, hunger, bad quality territories, dying earlier, etc.

true
Why evolution is a false theory?
Being a theory, evolution (or rather "natural selection") is neither "true" nor "false". A theory is put forward as a possible explanation for a phenomenon that can be observed but not easily explained. There are many "facts" that are offered as evidence of "natural selection" being a good explanation for the huge variety of life on Earth and for the fact that, undoubtedly, species appeared and disappeared over the course of many millions of years, but not everyone is convinced by such "facts". There are other, alternative theories, such as creationism, lamarkism, or even extra-terrestrial intervention, but I'm afraid they're even less convincing than natural selection.

Evolution and natural selection stop if groups of a species are isolated from each other... true or false?
False. Isolation promotes natural selection of the unique mutations and recombinations in an isolated population, thus leading to evolution.
