Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.803\% 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 additional words.
Options:
[a] COC(CNC(=O)c1cn(C)c2ccc(S(=O)(=O)N3CCOCC3)cc2c1=O)OC
[b] COc1cc2c(cc1OC)-c1nnc(-c3cccs3)n1C1(CCCC1)C2
[c] O=S(=O)(c1ccc2ccccc2c1)N1CCN(S(=O)(=O)N2CCCCC2)CC1
Answer: b. COc1cc2c(cc1OC)-c1nnc(-c3cccs3)n1C1(CCCC1)C2
