A black body is continously radiating energy at a temperature of 2880 k if `U_(1) ,U_(2)` and `U_(3)` are the amount of radiation measured between the wavelength 599 & 600 nm , 999 & 1000 nm & 1499 & 1500 nm respectively then (wires constant b = `2.88 xx 10^(26) ` kmk)

A

`U_(2) lt U_(3)`

B

`U_(1) = U_(2) = U_(3)`

C
