Which characteristic of coaxial cables makes them suitable for EMI-prone environments?

Explanation:
Shielding blocks external electromagnetic interference. A coaxial cable surrounds the signal on the inner conductor with a conductive shield (such as braided or foil) and a grounded outer jacket. This shield acts as a barrier to external EM fields, preventing interference from creeping in and keeping the signal from radiating noise outward. In environments with lots of EMI, that shielding is what makes coaxial cables reliable. Other characteristics like impedance, flexibility, or loss relate to matching, handling, or attenuation, but they don’t address EMI suppression as directly as shielding does.
