The the object that has the less mass will travel faster because let’s say for example the first object has the mass of M and the second object has the mass of 2M and if the momentum is equal so that means that we could divide M with M and we would get V1=2V2 (being V1 the velocity of the first mass and V2 the velocity of the second one) I hope I helped you out.

In option A there are two resistors in which two terminals of resistors are connected with the terminals of battery so here they are connected in parallel.
In option B all resistors and battery is connected in a single loop so it is a series combination of all.
In option C all three resistors are connected by their terminals to a single battery so here all three resistor are in parallel with the battery.
In option D only one resistor is connected in series with a battery as one single loop is there.
So in the above all cases two resistors are in parallel with battery in option A
