Task: Answer the multiple-choice question.
Query: Which drug exhibits a 12.106\% 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] COc1ccc(Cl)cc1-n1c(C)ccc1C
[b] Cc1cc(N2CCN(C)CC2)nc2ccc(NC(=S)N3CCN(c4cccc(Cl)c4)CC3)cc12
[c] Cc1cccc(NC(=O)C2CC(=O)n3cnnc3S2)c1
[d] CC(/C=N/NC(=O)COc1ccccc1C)=N\NC(=O)COc1ccccc1C
Answer: a. COc1ccc(Cl)cc1-n1c(C)ccc1C
