The electrodes responsible for collecting the signal data in an externally stimulated EMG activity experiment are both positive and negative electrodes (option d).

Here's a step-by-step explanation:

1. In an EMG (Electromyography) experiment, electrodes are used to detect and record the electrical activity produced by skeletal muscles.

2. The positive and negative electrodes are placed on the skin over the muscle to be studied. The positive electrode is placed in the direction of the muscle fibers, and the negative electrode is placed at the end of the muscle fibers.

3. When the muscle is externally stimulated, it generates an electrical signal. This signal is picked up by the electrodes.

4. The positive electrode detects the onset of the electrical activity, while the negative electrode detects the end of the activity.

5. The difference in electrical potential between the positive and negative electrodes is what constitutes the EMG signal. This signal is then amplified and recorded for analysis.

So, both the positive and negative electrodes are responsible for collecting the signal data in an EMG experiment.
