Answer:
C. Traje de luces
Step-by-step explanation:
Traje de luces translates to suit of lights. It is the traditional outfit that the Spanish bullfighter wears in the bullring. The term refers to 'lights' because the material of the outfit reflects gold and silver.
‘Banderilla’, ‘picador’ and ‘matador’ do not refer to the clothing of the bullfighter.
