for AC b i equated many=some and chose e instead as it was a statement for “most” systems….but suppose since it is ratios in consideration similarity weighs more (hence not requiring exact no of planets to match) making b the correct answer choice….

does my line of reasoning sound right??

Yes, you are right. The argument is discussing ratios rather than a set number of planets. The flaw is that there is no justification for presuming that 1/9th of planets in other solar systems will have life, because other solar systems might be nothing like ours
