Answer:
The correct answer is 1. EEG.
EEG or electroencephalography is a technique used to measure the electrical activity of the brain.
8 to 16 pairs of electrodes are placed on the scalp which record the electrical activity or impulses (in volts) generated by thousands of neurons or nerve cells present in the brain.
It provides the real-time imaging of the electrical activity of the brain.
The recorded impulses are first sent to the amplifier as the magnitude of the brain's electrical impulses is very low.
The amplifier then amplifies the results and show it on the screen in the form of voltage units.

radiant. energy into chemical energy
D. Conclusion
After gathering data in support of a hypothesis, you can make a conclusion.
A hypothesis has to be tested multiple times by multiple researchers to become a theory. A fact has to be proven multiple times as well (but theory is a much better word).
