Answer to Question 1

C

Answer to Question 2

Few molecules, such as TiO, are durable enough to exist in the photospheres of the coolest stars and thus be visually detected. Most less-durable molecules can exist only at much colder temperatures, where they give off infrared, microwave, or even radio emissions from their rotational and vibrational transitions.
