Which of the following statements about ocean currents is/are correct? A. The cold currents carry water from polar or higher latitudes to tropical or lower latitudes. B. Labrador is a warm current. C. Areas where warm and cold currents meet provide world's best fishing grounds.

Cold ocean currents flow from polar/higher latitudes towards tropical/lower latitudes, carrying cold water (A is correct). The Labrador current is a COLD current, not warm, flowing from the Arctic along the coast of Labrador (B is incorrect). Where warm and cold currents meet, plankton thrives due to mixing of nutrients, creating the world's richest fishing grounds like the Grand Banks off Newfoundland (C is correct). Hence A and C are correct.
