What do we observe in the spectral lines of stars as they become hotter and hotter? Select one: OA. We start seeing more red lines. OB. We start seeing more blue lines. O C. We start seeing more lines from ionized elements. O D. We start seeing more lines from molecules. We receive complaints from the star, such as, "Why do you need to get all up in my grill, cranking the heat up O E. like this?"
