I had a bit of an issue with this one. After your explanation, and upon further review of the answer choices, I see another potential approach, so correct me if I'm mistaken. Foremost, the question was about the hypothesis specifically, so the intro to the scientist's comment is a bit of a red herring. Keeping that in mind, you can (sort of) rule out a few answers that are out of the scope of the question (tricky, because they're still relevant to the passage...just not to the hypothesis).
-in B "rate" wasn't mentioned, and it seems to reference the antibiotic (antibacterial) properties. It neglects the hypothesis regarding access to nutrients. Additionally, Other weird assumptions are needed to make this work, so it's not a good choice.
-with C, similar to B, "speed" isn't mentioned and we have no way of knowing how the pipelines impact the speed of growth. This one is a bit closer, because it does touch on the nutrient aspect, but falls short as it would potentially indicate that either the pipelines aren't really needed. Too many questions remain for this to strengthen the hypothesis.
-I foolishly chose D, because I falsely tied the nutrient pipeline to the antibacterial properties. But after reviewing the video, I realized that (a) "better able" makes a comparison that wasn't established, and (b) the answer isn't addressing the nutrient pipeline, more importantly.
-E seemed to weaken the argument, given the term "essential". This leaves you wondering why they are "more likely to die", so... too many additional details must be assumed to make this a feasible choice.
That leaves A, and my initial concern was that this was referencing a different circumstance, but the word "essential" still holds, in that inner bacteria need the nutrients, regardless of the process/structure. 'A' is the answer that best addresses the nutrient-transport problem, and proposes a different method of delivery in absence of the pipelines, thus supporting the hypothesis. It's along the lines of "inner bacteria absolutely need the nutrients from the surrounding environment, and if phenazines are NOT found, then other structures also yield the same result".
Make sense?
