The correct answer is A. <span>They both follow the double verb rule even though there is a preposition in the middle, so the next verb always remains in the infinitive. For example: me voy a hacer eso - I am going to do that; acabo de dormir - I just stopped sleeping. B is incorrect because they need to be conjugated, and the verb that follows does not; C is incorrect because they are normal Spanish words which would be understood anywhere where Spanish is spoken; D is incorrect because they are actually antonyms, meaning they have opposite meanings.</span>
