I would answer with C. because it is stating that students should have a more low-carb high-vegetable base meal plan in school lunches. This fits the negative tone of the sentence and agrees with it, so this would be the answer.
A. could technically be correct, but it does not flow with the tone of the sentence, as it has a negative connotation
B. Doesn’t have anything to do with the topic sentence, obviously elimination.
D. also doesn’t have anything to do with the topic sentence. Wrong because there is nothing mentioned about meat or organic foods.
A participial phrase contains a participle, which is a verbal form with the endings -ed or -ing (or irregular, such as "written", as in "Written on monday (the piece was famous already on Tuesday)).
here the participle is "noted" and the whole phrase is this one:
Noted for her beauty
I believe the right answer is 1
Its motivation pretty postive
