Hey there! Not sure what form you’re using but the normal conjugations for leer are as so.
Yo: Leo Tú: Lees El/ella usted: lee nosotros: leemos vosotros: leéis ellos/ellas/uds.: leen
In this situation you are using the ellos ellas section so I’d say leen. But again not sure what form you’re using if you’re attempting preterite or such so I’d suggest googling leer conjugations and using SpanishDict. It’s a very reliable source for conjugations.
