ASAP PLEASE! WILL GIVE BRAINLIEST ANSWER! The pictures below show the wavelengths and intensities of electromagnetic radiations
rjkz [21]

As per Weins displacement law the wavelength of light for which we get the peak of the graph is always inversely proportional to the temperature.

So we can say

/lambda = \frac{b}{T}

So here if temperature becomes more cool then wavelength will increase

here we know that

\lambda_1 = 8500 A^o

\lambda_2 = 6000 A^o

\lambda_3 = 3500 A^o

It means the hottest star out of all three is star 3

and coolest star is star 1

now if we star 2 becomes cooler then it means its temperature will go near to star 1 and hence it will more look like to star 1.

So correct answer is

it will look more like Star 1
