Explanation:

With just a couple of rules, we are able to answer this question easily. First, when we have a compound subject joined by "and", the verb should be plural, since it refers to both elements in the subject. That is why letters A and B are wrong. Letter C, however, does present a verb with a plural conjugation, which makes it correct.

When a compound subject is joined by "or", and one of the elements is plural, the verb will agree with the element that is nearer. Letter D is incorrect because "attract" should agree with "corn" and not "seeds".
