I'm curious as to where it states that every year a new strain must occur. I understand that since one vaccine only protects against one strain, if a new strain is popular then it is best to get the new vaccine, but that is best represented in answer C.

If you picked C, you've picked the best wrong answer choice.
This question is a Necessary Premise question, so you need to start by isolating the conclusion. In this case, it's "every year it will be necessary to vaccinate high-risk individuals".
Now, what's missing from the argument that's required to support that conclusion?
Let's look at the premises: We know that the vaccine will only protect against the strain deemed most likely to be most prevalent each year. But nothing in the argument states that the same strain could not be the most prevalent strain for multiple years in a row. That's where answer choice D comes in.
As for choice C, it's not necessary that each vaccine protect against only one strain of the virus. It's only necessary that it protect against the most prevalent strain of the virus.
Hope this helps.

I agree. These questions and answers are not based on "How do they know which strain of the flu will be prevalent this year? The same vaccine could be used two years in a row"
You have to pick the best wrong answer. And how do you do that? Read the text and rely in that to draw pick the answer. Forget what you read in the news or saw on the CDC website. And don't leave any answers blank.
