@Yug.
Here they have Said that light circle means on i.e., the circle with white is on and the shaded circle is off. So binary equivalent is 10101100 & decimal equivalent is 127.

led on = logic 1.
led off =logic 0.
So the given binary code is 10101100.
So, the decimal value for that is 172. Hence option D is right.
led off =logic 0.
