Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 18.085\% 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] COCCC(=O)N1CCC(C(=O)Nc2ccc(Oc3ccccc3)nc2)CC1
[b] COc1cccc(CNC(=O)c2cccc(S(=O)(=O)N3CCN(c4ccc(F)cc4)CC3)c2)c1
[c] Cc1c(NC(=S)N/N=C/c2ccc(N(C)C)cc2)c(=O)n(-c2ccccc2)n1C
[d] CC(=O)c1sc(NC(=O)CN2C(=O)C3CCCCC3C2=O)nc1-c1ccccc1
