💡 Explanation
A large influx of freshwater disrupts the ocean's salinity gradient, reducing density and hindering the sinking of surface waters—a process called thermohaline circulation. Therefore, the AMOC weakens, rather than strengthens, because freshwater input counteracts density-driven sinking vital for its operation.
