Solutions:
As per the Question we have been asked to find the largest number from the given options.
The given options are
[tex] A. 6.1*10^{-7}\\
\\
B.4.1*10^{-7}\\
\\
C.3.1*10^{-8}\\
\\
D.5.1*10^{-8}\\
\\ [/tex]
As we know smaller the number in exponent , smaller is the number.
Here we have [tex] -8<-7 [/tex]
So now we just need to see the option A and B, just choose the number in decimal with larger value.
Hence the correct option is [tex] A \ 6.1*10^{-7} [/tex]
