Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 16.174\% 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: Cc1nnc(SCC(=O)Nc2ccc(O)cc2)c2ccccc12
b: CCN1C(=O)/C(=C\c2cccs2)C(C(=O)OC)=C1C
c: Nn1c(SCC(=O)NCc2ccc3c(c2)OCO3)nnc1C1CC1
Answer: b. CCN1C(=O)/C(=C\c2cccs2)C(C(=O)OC)=C1C
