Solution

The correct option is D $0.04 A$
The circuit is as shown as image 1.
As the lower diode attached to $100 Ω$ resistance is in reversed biased so, it is non-conducting.
Now, the circuit can be redrawn as image 2.
$∴$ Current through the circuit, $I = \frac{V}{R}$ $= \frac{10}{250} = 0.04 A$
