Assertion: Acceleration of charged particle in non-uniform electric field does not depend on velocity of charged particle.
Reason: Charge is an invariant quantity. That is amount of charge on particle does not depend on frame of reference.

If both assertion and reason are true and reason is the correct explanation of assertion.

If both assertion and reason are true but reason is not the correct explanation of assertion.

If assertion is true but reason is false.

If both assertion and reason are false.

Solution

If both assertion and reason are true but reason is not the correct explanation of assertion.

If both assertion and reason are false.

$\bar{α} = \frac{q \bar{E}}{m}$

Where $α$ = acceleration ( m/s² )

q = charge ( coulomb )

m = mass ( kg)

E = electric field ( volt × m^-1 )

As $\vec{E}$ varies so does $\bar{α}$ , it does not depend on its velocity.
