Correct Option
The Democratic Republic of the Congo (DRC) is the world's largest producer of cobalt, contributing approximately three-fourths (70-75%) of the global supply. Cobalt is a critical mineral essential for the manufacture of lithium-ion batteries, which power electric vehicles, mobile phones, and various other electronic devices. While other nations like Russia and Australia also produce cobalt, their output is significantly lower than that of the DRC.
