Task: Answer the multiple-choice question.
Question: Which drug exhibits a 6.660\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) C=CCn1c(CSc2ccc(C)cc2)n[nH]c1=S
b.) Cc1ccc(C2(CCN)CCOC(C(C)C)C2)cc1
c.) CS(=O)(=O)c1ccc(C(=O)Nc2cccc(-c3nc4ccccc4[nH]3)c2)cc1
d.) COCc1cc(C)nc(OCC(=O)N/N=C/c2ccc(-c3cc([N+](=O)[O-])ccc3Cl)o2)c1C#N
Answer: d. COCc1cc(C)nc(OCC(=O)N/N=C/c2ccc(-c3cc([N+](=O)[O-])ccc3Cl)o2)c1C#N
