Solution

The correct option is A $0.4 S$

Current $I = 4 A$
Potential Difference $V = 10 V$

Using Ohm's law
$\Rightarrow \frac{V}{R} = I$
$\Rightarrow R = \frac{V}{I}$

$R = \frac{10}{4} Ω$
Since, $C o n d u c t a n c e (C) = \frac{1}{r e s i s t a n c e (R)}$
$\Rightarrow C = \frac{1}{R} = \frac{4}{10} = 0.4 S$
