If the forward bias on p-n junction is increased from zero to \( 0.045 \mathrm{~V} \), then no current flows in the circuit. The contact potential of junction i.e. \( \mathrm{V}_{\mathrm{B}} \) is
(a) zero
(b) \( 0.045 \mathrm{~V} \)
(c) more than \( 0.045 \mathrm{~V} \)
(d) less than \( 0.045 \mathrm{~V} \)
