How long are temporary replacement certificates valid?

Answer: C — 30 days

Temporary replacement certificates are typically valid for 30 days. This time frame allows individuals who have lost or misplaced their original certificate sufficient time to apply for a replacement while still maintaining their eligibility to perform their duties. The 30-day validity ensures that the temporary status is just enough to bridge the gap without leaving any extended uncertainties. This is a standard practice in various certification programs to reduce the risks associated with operating without a valid credential.
