Variation of radiant energv emitted by sun. filament of tungsten lamp and welding arc as a function of its wavelength is shown in figure. Which of the following option is the correct match?

• A

  Sun -${\mathrm{T}}_1$,  tungsten filament -${\mathrm{T}}_2$, welding arc -${\mathrm{T}}_3$,

• B

  ${\text{Sun-T}}_2, \mathrm{tungsten} \mathrm{filament}-{\mathrm{T}}_1, \mathrm{welding} \mathrm{arc} -{\mathrm{T}}_3$

• C

  $\mathrm{Sun}-{\mathrm{T}}_3, \mathrm{tungsten} \mathrm{filament} -{\mathrm{T}}_2, \mathrm{welding} \mathrm{arc} - {\mathrm{T}}_1$

• D

  $\mathrm{Sun}-{\mathrm{T}}_3, \mathrm{tungsten} \mathrm{filament}-{\mathrm{T}}_1, \mathrm{welding} \mathrm{arc} -{\mathrm{T}}_2$
