Answer:

B

Step-by-step explanation:

4 laps were ran between her 3rd and 7th lap (inclusive) and the duration increased by 14 seconds

But just 2 laps were ran between her 7th and 9th lap and the duration increased by 11 seconds

So obviously the lap duration increased faster between the 7th and 9th lap
