Hola,la respuesta es la letra b las esculturas del museo no se pueden tocar eso está prohibido.^_^
The answer is the letter b, I assure you, I speak Spanish from birth, it is my mother tongue.
I’m fluent, but if you are having a hard time with conjunctions you can get the app SpanishDict and it shows you all the different conjunction’s
Oof your on your own for this one good luck
