Solution

The correct option is A 0°
The magnitude of the force experienced by a current carrying conductor in a magnetic field is given by the lorentz force formula $q v B s i n θ$ .

$S i n θ$ is minimum at $θ = 0 °$ , $s i n (0^{0}) = 0$ .
$∴$ The force on the conductor is also 0.
Hence, option 'a' is the correct answer.
