Question: Match the items below with the correct type of supernova.

Supernovae are classified primarily by their spectra, and the presence or absence of lines from certain elements. Type I supernovae lack hydrogen lines in their spectra and are further divided into three subcategories: Type Ia, which shows strong silicon absorption lines; Type Ib, which lacks silicon absorption lines but shows helium; and Type Ic, which lacks both hydrogen and helium lines. Type II supernovae, on the other hand, show prominent hydrogen lines. The categorization of supernovae is crucial for understanding the processes leading to these stellar explosions and for using them as cosmic distance markers.
