The correct answer is C. Congress amended it to broaden the protection it offered.
Step-by-step explanation
The Americans with Disabilities Act of 1990 was a law enacted by the Congress of the United States Republic to establish parameters that prohibited discrimination against disabled people. However, this law must be amended because the courts where this law had to be interpreted, do it erroneously and the rights of disabled people who were looking for a job were affected and were discriminated against for their condition. Therefore, the correct answer is C. Congress amended it to broaden the protection it offered.
