Task: Answer the multiple-choice question.
Question: Which drug exhibits a 23.214% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: O=C(c1n[nH]c2ccccc12)N1CCCCC1
b: CC(NC(=O)C1(C)CC1(Br)Br)C(C)(C)C
c: NS(=O)(=O)c1ccc(N/N=C/c2ccccn2)c([N+](=O)[O-])c1
d: O=C(COC(=O)c1ccc2[nH]c3c(c2c1)CCCC3)Nc1ccc(Cl)cc1Cl
Answer: c. NS(=O)(=O)c1ccc(N/N=C/c2ccccn2)c([N+](=O)[O-])c1
