In triangle ABC, which side is opposite angle C?

In triangle $A B C$ , $A B = 8$ cm, angle $A=50∘A=50^\circ$ and angle $B=70∘B=70^\circ$ . Which complete opposite pair can be used in the sine rule?

$A B = 8$ cm and angle $B=70∘B=70^\circ$

$A C = 8$ cm and angle $C=60∘C=60^\circ$

$A B = 8$ cm and angle $A=50∘A=50^\circ$

$A B = 8$ cm and angle $C=60∘C=60^\circ$
