Answer:
<h2>D.</h2>
Explanation:
The given statement is
<em>"One should read this book".</em>
<em />
We can observe that the given statement has the work "should", which implicates an advice. So, the right answer must include a sentence with an "advacing tone".
The first choice, A, it doesn't have an advide, that sentence can be seen as a demand, an order, but with an infinitive verb.
The second choice, B, it's similar to choice A, it has a demanding tone, but without an infinitive verb.
The third choice, C, doesn't have neither an advice tone or an order tone.
The last choice, D, actually has the characteristic we need, the statement <em>"Se debe leer este libro", </em>has the word "debe" in it, which refers to an advice. This statement englobes the meaning of the given statement.
Therefore, the right choice is D.
