The graph shown in fig. represents energy density ${\mathrm{E}}_{\mathrm{\lambda }}$ versus $\mathrm{\lambda }$ for three sources : sun, welding arc and tungsten filament. For ${\mathrm{\lambda }}_{\max }$, correct combination will be
 

• A

  Sun-T₁, tungsten filament-T₂, welding arc-T₃

• B

  Sun-T₂, tungsten filament-T₁, welding arc-T₃

• C

  Sun-T₃, tungsten filament-T₂, welding arc-T₁

• D

  Sun-T₃, tungsten filament-T₃, welding arc-T₂,
