The correct answer is A. Charging by friction
Explanation
When someone rubs a comb with their hair when they are combing it and the hair sticks to the comb occurs a phenomenon called electrization, in which a neutral body becomes charged or loses an electrical charge (electrons). One way that electrization occurs is through the rubbing of two neutral bodies which causes one to be positively charged and the other negatively causing them to attract each other by magnetism. Therefore, the correct answer is A. Charging by friction

<h2>Scientists use a wide variety of techniques to monitor volcanoes, including seismographic detection of the earthquakes and tremor that almost always precede eruptions, precise measurements of ground deformation that often accompanies the rise of magma, changes in volcanic gas emissions, and changes in gravity.</h2>
Well, Mendeleev's Period Table is truly a genius discovery. Some say that he thought of it during his sleep.
It's also sometimes called a Periodic Table. Periodic Table helps to organize all of the elements based on their properties, and much more. It also includes a lot of important stuff, such as atomic masses.
