Answer:
The sentence that means "they greeted each other" in Spanish is:
C) Se saludaron
Explanation:
<em>Yo </em><em>me salude</em><em>/ Tu </em><em>te saludaste</em><em>/ Él se </em><em>saludo</em><em>/ </em><em>Ella se saludo</em><em>/ Nosotros </em><em>nos saludamos</em><em>/</em> <em>Ellos </em><u><em>se saludaron.</em></u>
A reciprocal verb is one that conjugates a pronoun according to the subject and syntactic function.
The verb<em> "Ellos"</em> can be changed by the reciprocal verb <em>"Se" </em>in the sentence.
And, "greeted each other" is in the past tense, so in Spanish this is translated as "<u><em>Saludaron</em></u>"
