C Correct answer
Explanation

Breccia is a sedimentary rock characterized by large, sharp angular fragments cemented together in a fine-grained matrix. Unlike conglomerate which has rounded pebbles, breccia's fragments are angular, indicating they were not transported far from their source. The other options (Emerald, Lapis Lazuli, Turquoise) are gemstones/minerals, not rock types.
