The best answer for this sentence is B. Dígame.
Please correct me if I'm wrong!! I'd be happy to fix it!! :)
Well, that translates to when is the birthday of Jorge's mother, so you would say a date (for example, el tres de enero--it's the <u>(# of day)</u> de <u>(Month)</u>)
I’m not sure what you mean by affirmative but when adding pagar to a sentence that uses “ustedes” it would then become PAGAN.
