Responding to you guys' questions on
conditional/hypothetical sentences as answer choices (
like the one in E):

Yes, in this case, the conditional is wrong. That's because a conditional is not a firm enough weakener.
This is generally the case — a hypothetical does not necessarily weaken the argument. We need something that is
TRUE and will affect the argument in
real-time NOW (if it's true).
Here's an example:
Premise: Cats attract people in a positive way.
Premise: Using cats in any business will improve our sales.
Conclusion: We should use cats in our business (to attract positive attention and improve sales).
Let's take the conditional, "If the cats we use get sick and die, then their deaths will outweigh the positive effects of using cats in our business." Is this NECESSARILY a weakener? No, because the cats will only bring the negative effects if they die. If they do NOT die, then my argument is still going to hold. So this is just a conditional that does not affect the argument at all.
To expand this, what about
conditional/hypothetical answer choice in strengthen/assumption questions? -->
Typically, Weaken and Strengthen question types will rely on causal reasoning —
not conditional reasoning. So we can expect to see a correct answer choice that is stronger. Reasoning that attacks a premise/conclusion directly is more powerful than conditional reasoning, and so when both are present it's typically best to focus on the stronger, more direct answers rather than the conditional ones. I don't know that this is always true — it's more of a general rule of thumb that's true in MOST cases. I can't think of situation with an exception right now, but it's safe to say that this should be a "guiding principle" for you moving forward.
In
necessary assumption questions, we're looking for the answer choice that, if false, would destroy the argument. Sometimes this can be a conditional, and sometimes it can be a non-conditional. What matters here is that our answer choice HAS to be something that the argument needs in order to work successfully.
In
sufficient assumption questions, it's all about finding the correct answer choice that connects the evidence and conclusion in a way that makes the conclusion airtight. This can be conditional or non-conditional.
So, for assumption questions, whether an answer choice is conditional or not matters less. For weaken/strengthen, be suspicious of conditionals but make sure you're thinking about which one directly weakens or supports the premises/conclusion of the argument.

Magoosh. She had been extremely helpful!
I will update this post if I meet any cr problems that have conditional/hypothetical answer choice as correct answer choice for all of us to learn. _________________
