B. A short thin wire
C. A short thick wire
D. A long thick wire

Answer 1

b

Answer 2

thanks :)

Answer 3

\[R=\rho\frac{L}{A}\]

Therefore to decrease resistance, you need low L and high A
If we ignore resistivity (rho) because you don't mention it, we assume it's the same material wire.
Then least resistance will be the lowest length and highest area.
Answer: Short-thick wire.
