While the bride in B tosses her bouquet, you can toss out that sentence because it uses "prodigious" as a noun instead of an adjective. Ellen's acting goals in A could best be described as "modest" or "unassuming," the very opposite of "prodigious," if she is happy with a tiny part of only one line. In C, "run-down," "shabby," and "dilapidated," come to mind as good substitutes for "prodigious." That leaves the brother in D and his seemingly insatiable craving for pasta.
