Solution

The correct option is B $C o u l o m b / (K g / s)$
$μ = \frac{v}{E} = \frac{(m e t e r) / (s e c o n d)}{(f o r c e) / (C o u l o m b)} = \frac{(C o u l o m b) \times (m e t e r) / (s e c o n d)}{(m a s s) \times (m e t e r) / {(s e c o n d)}^{2}}$

$= \frac{(C o u l o m b)}{(m a s s) / (s e c o n d)}$

$= C o u l o m b / (K g / s)$
