D. likelihood that should be likelihood of (for rating is also off)
E. that rates implies that the scale itself is doing the rating when the scale is in fact used to do something.

I beg to disagree with the OA provided.

What bothers me in C is the construction "likely ... will be to". :-(

D seems the best among the provided options. "likelihood that ... x will happen", is the same as saying "probability that ... x will happen"

@Iceman: That is the same thing that set me thinking too and I striked out C. But Jim's absolutely right. Likelihood of is more idiomatic that likelihood that. I guess that's the difference between experts and us! :)

Thanks.
