Answer:
Correct Answer: C
Solution:
[c] $ \because $ $ 10^{6} $ rupees are spent in 1 sec.
$ \therefore $ $ 6.023\times 10^{23} $ rupees are spent in $ \frac{1\times 6.023\times 10^{23}}{10^{6}} $
$ \sec =\frac{1\times 6.023\times 10^{23}}{10^{6}\times 60\times 60\times 24\times 365} $ years $ =19.098\times 10^{9} $ years
