The North Atlantic Drift and the Brazil Current are both warm ocean currents and hence, option 2 is the correct answer. To elaborate further:

1. Kuroshio is a warm current along Japan`s east coast, but California current is a cold current flowing southwards along the western coast of North America.

2. North Atlantic Drift, also known as the Gulf Stream, is a warm current in the Atlantic ocean flowing from the Gulf of Mexico towards Europe. Brazil Current, found in the South Atlantic Ocean, is a warm current flowing southwards along the eastern coast of South America.

3. Canaries and Benguela Current are both cold currents. Canary Current, a cold current on the African west coast, flows south, and Benguela, a cold current on the African south-west coast, flows north.

4. West Wind Drift, also known as the Antarctic Circumpolar Current, is a cold current flowing eastwards around the Antarctic, and Falkland current, another cold current, flows northward along the Atlantic coast of Patagonia.

In conclusion, the only option featuring two warm currents is option- 2.
