Number of rupees spent in one second =$10^5$
Number of rupees spent in one year$=10^6\times 60\times 60\times 24\times 365$
Avagadro's number of rupees will be spent=$\large\frac{6.02\times 10^{23}}{10^6\times 60\times 60\times 24\times 365}$
$\Rightarrow 19.089\times 10^9yrs$
$\Rightarrow 1.9089\times 10^{10}yrs$
Hence (c) is the correct answer.
