A neurophysiologist investigated the latency of the patellar reflex (knee-jerk reflex) in six healthy adult subjects. Using surface electromyography (EMG) electrodes on the quadriceps femoris muscle, the time elapsed between the mechanical tap on the patellar tendon and the onset of the muscle's electrical activity was recorded.
The latencies recorded for the six subjects are shown in the table below:
| Subject | EMG Latency (ms) |
|---|---|
| A | 24.5 |
| B | 28.2 |
| C | 21.0 |
| D | 32.4 |
| E | 25.8 |
| F | 22.1 |
Which of the following is the median latency of the patellar reflex for these subjects?

25.67 ms25.67\text{ ms}25.67 ms
