A clothing corporation argues that it needs a tariff so workers are not laid off. This is an argument for

an infant industry***
job protection
national security
environmental standards
protection from dumping

Am I correct?

No, not correct.

Then it would be job protection(?)

yes

Thank you, would it be alright if you could check my other economics question?

Yes, you are correct. The argument given by the clothing corporation, stating that they need a tariff to avoid laying off workers, is an argument for job protection. By implementing a tariff, the corporation aims to protect domestic jobs and prevent workers from being replaced or losing their jobs to foreign competition.
