We can use Wien's displacement law:

λ_max = 2.898 × 10^-3 m K / T

where λ_max is the wavelength of maximum intensity and T is the temperature in Kelvin.

Substituting the given values:

1.000 × 10^-6 m = 2.898 × 10^-3 m K / T

T = 2.898 × 10^-3 m K / 1.000 × 10^-6 m

T = 2,898 K

The closest answer is C) 2898 K.
