Which one of the following pairs is not correctly matched ?

The Gulf of California, also known as the Sea of Cortez, is located entirely within Mexico, bounded by the Baja California peninsula and the Mexican mainland [t2][t6]. While it is south of the US state of California, the body of water itself is not in the USA [t3][t8]. Other pairs are correctly matched: Baffin Bay is located between Canada (Baffin Island) and Greenland [c3][t7]. The Caribbean Sea borders several Central American nations including Honduras to the east [t3][t5]. The Gulf of Panama is a large body of water on the Pacific coast of Panama, which borders Colombia to its south [t3][t5]. Although some sources mention hurricanes in the 'Gulf of California, USA' in a general regional context [c5], geographical mapping strictly places the Gulf within Mexican territory [t2][t6]. Therefore, option 2 is the most inaccurate match.
