This is an interesting question - a bit weird, but an easy question.
1. The answer I was expecting was something related to the main point - sales success. I did not find anything about sales and was surprised 😮
2. Cleaning of every household the object seems to be of a secondary point but still a part of the argument. Anytime I see sales, I really assume they’re gonna dive into the selling process.
3. Option C is a bit of a niche out of scope option since it talks about plastics. What about wood floors or tile counters or metal objects? Plastics seems to be a niche a subsection and a subset….
4. Option E is the opposite. It strengthens the argument. It cannot be the correct answer. If you picked E, this is a common problem where you solve the question but pick the opposite answer. Make sure you come up with the system that allows you to pick the strength or the weekend. I used to draw an arrow up or down to help me understand strengthen the weaken or undermine And not accidentally picked the opposite.
5. C would be the only answer choice that undermines the argument.
