Q11=D, This is because the ball cannot have the same Gravitational Potential energy as it started or more hence it cant be A,B,C.
Q32=D, This is because in A the fuse protects northing, in B only the first lamp, in C only the 2nd lamp, in D it protects both.
Hope it helps :)

11) D .. they say energy is "lost" in th form of heat .. so the ball doesnt have that much of energy left to match the original position
remember always a body undergoing a free fall NEVER exceeds its starting position .. here it NEVER exceeds C
32) D again .. ;ets look at A .. fuse in parallel so protects neither of the lamps .. in B only one lamp is protected and also in C only one lamp is protected .. in D the fuse is placed in "beginning" of the circuit so both are protected
