Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -3.281\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) CCn1c(SCC(=O)OC)nnc1-c1ccccc1
(b) Nc1nc(SCC(=O)Nc2ccccc2Sc2ccccc2)n[nH]1
(c) CC(C)COc1ccc(C(=O)N(Cc2ccco2)C2CCS(=O)(=O)C2)cc1
Answer: a. CCn1c(SCC(=O)OC)nnc1-c1ccccc1
