Answer:

B. Double

Step-by-step explanation:

As we know that the magnetic force on moving electron is given as

$F = q(\vec v * \vec B)$

now we will have

$F = qv B sin\theta$

here we know that the velocity of the electron is doubled and rest all components remains the same

so we will have

$F' = q(2v)B sin\theta$

so the new force will be double that of initial force on the electron so correct answer will be

B. Double
