Explanation:

For option A the target is 47 and achievement is 46, so Performance = $\frac{46}{47}$ × 100 = 97.87%
For option B the target is 83 and achievement is 79, so Performance = $\frac{79}{83}$ ×100 = 95.18%
For option C the target is 90 and achievement is 87, so Performance = $\frac{90}{87}$ × 100 = 96.66%
For option B the target is 97 and achievement is 84, so Performance = $\frac{84}{97}$ × 100 = 86.60%
