Since power is given heat = I^2 x R x t, since I^2 R is the same for both resistors, neither will overheat.

Answer is wrong. Because we doing in project side in small value of resistors are easily access the heat.

33 Ω resistor will overheat as the connection is parallel it's not specific. So, the Answer is A.

I agree that the connection is not clear. If connected in series then option D otherwise option A.

Option D is correct because in // any type of load take current according its capacity ( Rating )

Since both resistors are connected across the voltage is in parallel so the option D is correct.

Power consumed by each of them is same so both of them get equally heated.

Heat is I^2R. This loss is more in 33 ohm resistor. Option A is correct.

Both the resistors have same power rating so no one will be heat up.

Equal rating not given, why you people calling equal rating?
