a.) A better option for free and natural communication
Explanation:
Oralism was contested several times before giving way to sign language because sign language was understood and deemed as the only language to reach the generality of the people while oralism was understood only by those that had a discursive consciousness.
As such due to the contradictions that would come up as a result of contradictions of life experiences, some participants in the use of oralism also used sign language to teach their colleagues that could not learn through oralism
Therefore, sign language is seen to be a better option than oralism due the ability for participants that use sign language being able to have Deaf cultural competencies making sign language a more natural form of communication for the participants.
