D-the support that scientists have given to the Deaf community

Explanation:

While Alexander Graham Bell's invention of the telephone favors the non-deaf people around the world, however, according to Bell, the invention of the telephone came out from the need to make the deaf see what they couldn't hear. Thus, the telephone by Bell was originally in design intended for the deaf.

On the other hand, Robert Weitbrecht's invention of the Teletypewriter was also an invention designed purposely for the deaf, in order to let the deaf communicate messages over a long distance through telephone lines.

Hence, In comparing Alexander Graham Bell to Robert Weitbrecht, we can see "the support that scientists have given to the Deaf community."
