Answer:
Juana es conservadora también. (D)
Explanation:
When talking about "También" it means that everything said before applies to the person you want to talk about right away.
By saying that if Eduardo es conservador, it can be said that the next person is also conservador.
The word conservador is a masculine adjective, but when it refers to a woman the adjective becomes feminine.
Él es conservador / Ella es conservadora
