JEE Main 2020 Physics question

When a diode is forward biased, it has a voltage drop of 0.5 V. The safe limit of current through the diode is 10 mA. If a battery of emf 1.5 V is used in the circuit, the value of minimum resistance to be connected in series with the diode so that the current does not exceed the safe limit is-

• (A)300
• (B)50
• (C)100 Correct
• (D)200
