Answer
The upthrust in sea water (F2) is more than the upthrust in river water (F1). Hence, F2 > F1.
As we know that the sea water is denser than river water, and if the density of the liquid is more it exerts more buoyant force. Hence, the body in sea water will experience more upthrust than in river water.
