Since diode is silicon so forward drop at diode is 0.7V remind voltage of Vin = 12-0.7 = 11.3

The silicon has 0.7 Cutoff voltage, So answer is11.3v/// Mostly used PN junction is Silicon.

First active diode need for 0.7 voltage.
Since the voltage across R1 = 12-0.7 = 11.3.
Since the voltage across R1 = 12-0.7 = 11.3.

0.7 is the Voltage across the pn diode so according to the kvl answer is 11.3

0.7v is Barrier Voltage which must be applied for diffusion to happen.

@Girish Vsi is voltage of silicon which is 0.7v it is constant
