Two uniforms discs of equal mass but unequal radii are mounted on fixed horizontal axiles. Light strings are wrapped on each of the discs. The strings are pulled by constant equal forces F for same amount of time as shown in the figure

Angular momenta of discs are L1 and L2 and their kinetic energies are K1 and K2. Which of the following statements true –
`L_(1) = L_(2)`
`L_(1)ltL_(2)`
`K_(1)gtK_(2)`
`K_(1)=K_(2)`
