Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.366\% 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 other words.
Options:
a. COC(=O)C1=C(c2ccc(S(C)(=O)=O)cc2)C[C@@H]2CC[C@H]1N2C(=O)NCCO
b. Cc1c(C)c(C)c(/C=[N+](/C)[O-])c(C)c1C
c. Cc1ccc(CNC(=O)/C=C/c2ccc(Br)o2)cc1
d. Cc1ccccc1-c1cc(C(=O)N/N=C/c2cccnc2)c2ccccc2n1
Answer: c. Cc1ccc(CNC(=O)/C=C/c2ccc(Br)o2)cc1
