Oh this is no biggie, the answer for this is B because that is the only option that doesent include a chemical reaction, heres a good tip: If the statement says that the material REACTS with another then that is an automatic chemical property because it is a chemical reaction, same goes with rust. Rust is a chemical reaction because thats how the metal REACTS with the moisture and air 

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."
