Task: Answer the multiple choice question.
Query: Which compound has a 6.891\% 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, d, or e without using any additional words.
Options:
(a) CC(=O)C1=C(C)N(Cc2ccccc2)C(=O)N[C@H]1c1cccs1
(b) O=C(Nc1c(F)cc(F)cc1Br)c1cc(-c2ccccc2)on1
(c) CSC1=C(C#N)C(CC(C)C)C(C(C)=O)=C(C)N1
(d) CCOc1ccc(CCNC(=O)COC(=O)CNS(=O)(=O)c2ccc(NC(C)=O)cc2)cc1OCC
(e) O=C(Nc1ccc(Br)cc1)c1cccc(N2C(=O)C3C4C=CC(C4)C3C2=O)c1
Answer: c. CSC1=C(C#N)C(CC(C)C)C(C(C)=O)=C(C)N1
