Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.556% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a.) COc1ccc(CCNC(=O)CSCc2ccc(Br)cc2)cc1OC
b.) Cc1ccc(CNC(=O)c2ccc(N3CCC4(CC3)CC(c3ccccc3)=NO4)c([N+](=O)[O-])c2)cc1
Answer: a. COc1ccc(CCNC(=O)CSCc2ccc(Br)cc2)cc1OC
