Task: Answer the multiple choice question.
Question: Which drug exhibits a 5.258\% 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.) CCc1ccc(/C=C2/C(=O)N(C)C(=S)N2CC(=O)OC)s1
b.) Cc1cccc(C(=O)Nc2cc(Cl)ccc2-n2cncn2)c1[N+](=O)[O-]
c.) COC(=O)c1cc(=O)c2cccc(OC)c2[nH]1
d.) O=C(CN(c1ccc(Br)cc1)S(=O)(=O)c1ccc(Cl)c([N+](=O)[O-])c1)NCCc1ccccc1
Answer: c. COC(=O)c1cc(=O)c2cccc(OC)c2[nH]1
