• A. $\alpha -$rays
• B. $\beta -$rays
• C. $\gamma -$rays
• D. None of these

Answer 1

The correct option is C $\gamma -$rays

Rays consist of charged particles will get deflected by the magnetic field.

$\alpha -$rays $:$ positively charged
$\beta -$rays $:$ negatively charged
$\gamma -$rays $:$ neutral

Therefore, $\gamma -$rays will not get deflected by magnetic field.
