This question tests our understanding of quantifier language and structure. The initial passage makes a statement using most and concludes a reversal of this statement.
A -most-> B, therefore B -most-> A
Using "likely" is the same as "most" in this context.
We are looking for an answer choice that does the exact same thing structurally, and this is what answer choice A does.
Reverses the most statement using "likely".
I hope this helps. Please let me know if you would like me to elaborate further or have any other questions.
