Here's the solution to your question:

Q=10 coulomb,
resistance=50 Ohm,
w=4000j,
V=W/Q
V=4000/10=400Volt,
V=IR,
400=I(50),
I=400/50=8A.

Hence, Correct Answer is Option C

To calculate the resistance of the resistor, we can use the formula:

Resistance (R) = Work (W) / Charge (Q)

Given:
Work (W) = 4000 Joules
Charge (Q) = 10 Coulombs

Plugging in the values:

R = 4000 Joules / 10 Coulombs
R = 400 Ohms

Therefore, the resistance of the resistor is 400 Ohms.
