A1
B2 ✓ Correct
C3
D4
Correct answer: (B) 2
Explanation
Exactly two years exceed a 6 percent rise, so that is the answer.
From 2019 to 2020 office F rises from 264 to 280, about 6.06 percent.
From 2021 to 2022 it rises from 252 to 292, about 15.87 percent.
Both of these exceed 6 percent.
No other year's rise exceeds 6 percent.
So exactly two years qualify.
