The correct answer is:
red
Given, resistance of carbon resistor
$R=4.7 \mathrm{k} \Omega \pm 5 \%=47 \times 10^2 \Omega \pm 5 \%$
The colour of four bands will be $4 \rightarrow$ yellow
$\begin{aligned} & 7 \rightarrow \text { Violet } \\ & 2 \rightarrow \text { Red } \\ & \pm 5 \% \rightarrow \text { Gold }\end{aligned}$
Thus, colour of third band is red.
$R=4.7 \mathrm{k} \Omega \pm 5 \%=47 \times 10^2 \Omega \pm 5 \%$
