Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 6.286\% 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 other words.
Options:
a. CC1(C)Cc2ccccc2C(/C(C#N)=N/O)=N1
b. COc1cc(/C=C/C(=O)Nc2nc3ccc(S(=O)(=O)N(C)C)cc3s2)cc(OC)c1OC
c. COc1ccc(-n2nc([N+](=O)[O-])c(=NCCc3ccc(C)cc3)n2O)cc1
d. CCOc1cc(C(=S)N2CCCC2)ccc1OC
e. O=C(Nc1ccc(C(=O)O)cc1)/C(=C\c1ccccc1)NC(=O)c1ccco1
Answer: a. CC1(C)Cc2ccccc2C(/C(C#N)=N/O)=N1
