Should be C?
Not sure though, best of luck
Whatever you want to put in it
the only difference between –er verbs and –ir verbs is the nosotros and vosotros forms.
<u>Example: Vivir (to live)</u>
<u>Nosotros:</u> vivimos
<u>Vosotros: </u>vivís
<u>Example: Volver (to return)</u>
<u>Nosotros:</u> volvemos
<u>Vosotros:</u> volvéis
there are several verbs that could be used here, but I would recommend gustar.
a mí me gusta el béisbol.
