The question is asking to match a list of ocean currents (List-I) with their corresponding names (List-II). The given options provide a code to indicate the correct matching pair.

List-I contains four ocean currents: Kuroshio, Humboldt, Beneguela, and Oyashio.

List-II provides the names of the ocean currents, but the specific pairings are not given in the question.

To find the correct answer, we need to analyze each option:

Option-1: The code given is 1 2 1 3 4, which means that Kuroshio is matched with Humboldt, Kuroshio again, Beneguela, and Oyashio. This option does not seem correct since Kuroshio is matched with two different names.

Option-2: The code given is 2 4 3 1 2, which means that Humboldt is matched with Oyashio, Beneguela, Kuroshio, and Humboldt again. This option also does not appear correct since Humboldt is matched with two different names.

Option-3: The code given is 3 4 1 3 2, which means that Beneguela is matched with Oyash
