Two ends of a conductor of varying cross section are connected to the terminals of a battery as shown in the figure. 1, 2 and 3 represent three different sections of the conductor. If ${\mathrm{i}}_1, {\mathrm{i}}_2 \mathrm{and} {\mathrm{i}}_3$ be the current flowing through these sections, then

• A

  ${\mathrm{i}}_1<{\mathrm{i}}_2<{\mathrm{i}}_3$

• B

  ${\mathrm{i}}_1<{\mathrm{i}}_2>{\mathrm{i}}_3$

• C

  ${\mathrm{i}}_1>{\mathrm{i}}_2>{\mathrm{i}}_3$

• D

  ${\mathrm{i}}_1={\mathrm{i}}_2={\mathrm{i}}_3$
