I don’t have the answer choices — can you post them?
In general: kinetic energy KE = ½ m v², so compare the product m·v². The object with the largest value of m·v² has the most kinetic energy.
Example: 1 kg at 10 m/s → KE = 0.5·1·100 = 50 J; 10 kg at 5 m/s → KE = 0.5·10·25 = 125 J, so the heavier, slower object has more KE.
