Cyril and methodius were missionaries to the slavs who

a. translated the bible into the new alphabet written for the slavic language
b. were excommunicated by pope gregory ii for their slavic writings supporting icons
c. were iconoclasts who spoke out against the use of holy images or sculptures
d. were scholars who established schools for the study of greek and roman history

I believe the answer is: translated the Bible into the new alphabet written for the Slavic language

The translation that Cyril and Methodious did make it possible for people in slavic area to understand the  teachings in the bible. It is believed that large population of catholics/christians in eastern europe today can be contributed to their efforts.
