No. of seconds Hema took to run the race = 109 seconds = 12 seconds faster than that of Chandni ∴ The time taken by Chandni to run the race  = (109 + 12) seconds = 121 seconds = 2 minutes 1 second (Since 60 seconds = 1 minute.)

Hema ran a race in 109 seconds. She ran 12 seconds faster than Chandni...
Given: Hema ran a race in 109 seconds. She ran 12 seconds faster than Chandni.

To find: How long did Chandni take to run the race?

Let's assume Chandni took x seconds to run the race.

According to the question, Hema ran 12 seconds faster than Chandni.

So, the time taken by Hema to run the race = x - 12 seconds

But we know that Hema took 109 seconds to run the race.

Therefore, x - 12 = 109

Solving the above equation, we get:

x = 109 + 12

x = 121 seconds

Therefore, Chandni took 121 seconds to run the race.

Hence, the correct answer is option 'D' - 2 minutes 1 second.
