Solution

The correct option is A $2, 000 m L$
To find the estimated volume of air filled in 1 second in the balloons, we will round off $13.$
Estimated volume of air filled in 1 second $\approx 10 m L$

$1 m i n = 60 s$
Duration for which the air is filled inside the balloons $= 3 \times 60 = 180 s$
Estimated duration of filling $\approx 200 s$

Estimated volume of air filled in total $\approx 10 \times 200 = 2, 000 m L$

Hence, option D is correct.
