Answer:
Certain aspects of the process are governed by federal laws.
Different states have their own laws governing aspects of the process.
Employers may offer an online application process.
Step-by-step explanation:
The first option is correct, as certain aspect is being covered by the federal law, and various others are being governed by the state laws. The second option is wrong as no kind of discrimination is allowed by federal law. And different states in the US have a different set of laws. The drug screening and criminal background checks are never prohibited but discrimination on their basis is not allowed. Hence this is not a correct option. And Its on Employer to offer an online application or not. And hence, the options mentioned in the answer section are correct ones.
