Explanation:

A thesis or thesis statement is one of the most important parts when writing an essay or developing an argument as it is the center of a position or argument the author wants to prove as valid. In general terms, for a thesis to be considered as effective it needs to express a position which means thesis statements that only express facts or rely on personal opinions or judgments are not effective and it also needs to be debatable which means if a thesis statement does not require evidence or supporting details to be proven as valid it is not effective. Considering this, the option that includes an effective thesis statement is "Bees are crucial part of any thriving ecosystem, including your garden" because this statement shows a clear position from the author which is the need of bees for the ecosystem and this statement needs to be developed through evidence that shows the reasons that make bees essential which means the thesis is debatable as well. Also, this thesis statement does not limit to a fact or opinion but introduces a claim or position.
