All the options involve multiplication or division. The number of significant numbers in multiplication and division is the same as the one with less number of significant figures.

So:


20.947cm*82.cm=1717.654cm^2=1.717654*10^3cm^2\approx1.7*10^3cm^2
192.1g/38.2mL=5.0287\ldots(g)/(mL)\approx5.03(g)/(mL)
372.0mol/0.75L=496(mol)/(L)=4.96*10^2(mol)/(L)
