i] its obviously R because you have one series Resistor in the path.

ii] although its also only one resistor but its in PARALLEL, meaning the resistance is affected by the other parallel resistor. and here's something, when ever you have two resistors connected in parallel and they're identical. then total resistance is half of one of the resistors.

for example, if you have to 5 ohm resistors then (1/5 + 1/5)^-1=2.5 which is half 5, so the answer for this part is 0.5R

iii] you have two series resistors so thats 2R and then the total resistance of the parallel ones which is 0.5R calculated from before, so its 2.5R

CHEMMASTER6000:
the law is in chemistry as well. didnt know it was part of physics.
