Final answer:
The correct fine amounts for ADA violations are not provided in the question's choices. Instead, the provided choices relate to OSHA violation fines, which can reach up to $70,000 for repeat or willful violations. ADA fines differ and are subject to federal guidelines based on the specific circumstances of each case.
Step-by-step explanation:
An employer who has repeatedly violated the Americans with Disabilities Act (ADA) may be subject to fines, but the question does not provide the correct answer options for ADA violations. The fines related to OSHA standards are different from those under the ADA. For OSHA, the maximum fine for a serious violation is $7,000, whereas repeat or willful violations can incur a fine up to $70,000. The ADA can impose penalties on businesses that fail to comply with its non-discrimination requirements. Penalties can vary based on the nature of the violation and history of previous violations. To determine the exact fine for ADA non-compliance, one would need to refer to current federal guidelines as they are subject to change and can differ based on the specifics of each case.
