Ihave a question that's confusing, will a large can of solids or empty can reach end of the ramp faster first in a can race? also will a small can of solids or empty can reach end of ramp faster first? explain briefly why you so much

The large can of solids will reach before the empty can reason being is it has more additional weight its like dropping a 1 pound weight compared to a 4 pound the 4 pound reaches faster because of the gravitational pull the size of the pull depends on the masses of the objects 

B. a circuit. i think

My answer is opptionc, just check with anyone else
