I believe it might be A. Damaged buildings.
B is a positive and so is Tourism.
If you look at the periodic table you will see the atomic number (the smaller number) which is 3. that identifies how many protons there are. since the lithium is neutral that means there’s a same amount of electrons.
therefore there’s 3 electrons and 3 protons
It's true because gravity retract everything.
