Help me out here it’s asking A^C U C^C

Answer: I, III, IV, VI, VII, VIII
Step-by-step explanation:
The complement of A means everything NOT in A: {I, IV, VII, VIII}
The complement of C means everything NOT in C: {III, VI, VII, VIII}
The union of A-complement and C-complement is Everything minus their Intersection {II and V} = {I, III, IV, VI, VII, VIII}
