Consider the following statements regarding acid-base theories:\n1. According to the Arrhenius concept, an acid increases H+ ion concentration in aqueous solution, while a base increases OH- ion concentration.\n2. The Brønsted-Lowry theory defines an acid as a proton donor and a base as a proton acceptor, which allows for acid-base reactions in non-aqueous media.\n3. All Brønsted-Lowry bases are also Lewis bases because they must possess a lone pair of electrons to accept a proton.\nWhich of the statements given above are correct?

Options:

• A: 1, 2 and 3
• B: 1 and 2 only
• C: 2 and 3 only
• D: 1 and 3 only
