C Correct answer
Explanation

Back-to-back registration is a security feature where designs printed on the front and back of a note align perfectly when viewed against light. The floral patterns on both sides are designed to coincide exactly, creating a complete image when superimposed. This precise alignment is difficult to achieve in counterfeiting. Optically variable ink changes color, watermark is a portrait visible against light, and latent image requires horizontal viewing.
