Problem statement: Answer the multiple-choice question.
Query: Which drug has a 12.498\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. O=c1[nH]c(=S)n(-c2ccccc2F)c(O)c1C=NCCN1CCNCC1
b. CC(=O)c1ccc(NC(=O)CS(=O)(=O)c2cn(CC(=O)N3CCOCC3)c3ccccc23)cc1
c. COc1ccc(S(=O)(=O)Nc2ccc(Cc3ccncc3)cc2)cc1OC
Answer: a. O=c1[nH]c(=S)n(-c2ccccc2F)c(O)c1C=NCCN1CCNCC1
