As we know, opposite poles of magnets attract each other. Then the possible combinations can be :

Either,

P - North, Q - South, R - North, S - South, T - North, U - South, V - North, W - South  

Or,

P - South, Q - North, R - South, S - North, T - South, U - North, V - South, W - North

Lets say if Q is S - South. Then, the only possible option is (B).

C

For an object moving with constant speed , speed is given by the ratio of distance travelled to the time taken by it. Hence, its SI unit is m/s.

Volume of an object is obtained by multiplying area of cross section to its height .Hence, its SI unit is m^3.
