<u>Right Answer:
</u>
<h2>Escribe
</h2>
This a sentence written in <u>present tense</u> with the<u> 3rd person singular</u> <em>ella</em> (she), because <em>La profesora</em> is a femenine subject.
Therefore the correct conjugation of the verb<em> </em><em>escribir </em>(to write) in present tense and indicative mode is <em>(ella) escribe</em> (she writes).
Now the whole sentence is:
<h2>La profesora <u>escribe</u> el examen
</h2>
(The teacher <u>writes</u> the exam)
<u>The other options are incorrect</u> because, although they are in <u>present tense</u> and<u> indicative mode</u>, the conjugation does not match with the subject of the sentence:
<em>(Yo) escribo</em> (I write)
<em>(Tú) escribes</em> (You write)
<em>(Ellos/Ellas) escriben </em>(They write)
