A) 34.76 years	B) 32.48 years
C) 33.31 years	D) 31.68 years

Answer & Explanation Answer: D) 31.68 years

Explanation:

We know that 1 year = 365.25 days

1 day = 24 hours

1 hour = 60 minutes

1 minute = 60 seconds

=> 1 Year = 365.25 x 24 x 60 x 60 Seconds

But 1 billion seconds = ?

1 Year = 365.25 x 24 x 60 x 60 Seconds

? = 1000000000 Seconds

$? = \frac{1000000000}{365.25 x 24 x 60 x 60} years$ = 31. 68 years.
