Task: Answer the multiple-choice question.
Question: Which drug exhibits a 15.897\% 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(-c2nnc(N)s2)cc1
b CCOC(=O)C1=C(CNCc2ccc(C)cc2)NC(=O)NC1c1cc(C)ccc1C
c CCCc1c(C)nn(C(=O)/C(C#N)=N/Nc2ccccc2[N+](=O)[O-])c1C
d CCNc1nc(NCC)nc(N/N=C/c2ccccc2)n1
Answer: c. CCCc1c(C)nn(C(=O)/C(C#N)=N/Nc2ccccc2[N+](=O)[O-])c1C
