d. No standard required.

Explanation: Under the "border search" exception to the Fourth Amendment, routine searches at the border (and its functional equivalent) may be conducted without a warrant, probable cause, or even reasonable suspicion. Courts have allowed routine baggage, vehicle, and person searches without any particularized suspicion (see, e.g., United States v. Ramsey; United States v. Flores‑Montano). However, non‑routine or highly intrusive searches (strip/body‑cavity searches, prolonged detentions to obtain evidence, and in some courts forensic searches of electronic devices) may trigger a higher showing—often reasonable suspicion or, in some circumstances, a warrant.
