A alternativa correta é a letra "a) I and III are correct." O papel tornassol é um indicador ácido-base que muda de cor em contato com soluções ácidas ou básicas. Quando em contato com ácidos, o papel tornassol vira vermelho, e quando em contato com bases, vira azul ou verde, dependendo da força da base. Portanto, a alternativa I está correta, pois o papel tornassol vira vermelho em contato com ácidos, e a alternativa III também está correta, pois o papel tornassol pode virar amarelo em contato com ácidos mais fracos e verde em contato com bases mais fracas.
