Task: Answer the multiple-choice question.
Query: Which drug has a 6.048\% 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, c, or d without using any additional words.
Options:
[a] O=C(COc1ccc(Cl)cc1)NCCS(=O)(=O)N1CCN(c2ccc(F)cc2)CC1
[b] O=C(COC(=O)Cn1cnc2ccccc2c1=O)NCC12CC3CC(CC(C3)C1)C2
[c] O=C(CSc1nc2ccccc2c(=O)n1CC1CCCO1)N1CCN(c2ccccc2)CC1
