Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.971\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CCOC(=O)CN1C(=O)S/C(=C/c2cccc([N+](=O)[O-])c2O)C1=O
b CC(=O)Nc1cc[n+](C(C)C(=O)c2ccc(Cl)cc2)cc1.[Cl-]
c COc1cccc(CNC(=O)C2CCCN(c3nn4c(=O)cc(C)nc4s3)C2)c1
d O=C(CCc1c[nH]c2ccccc12)Nc1ccc(S(=O)(=O)Nc2ncccn2)cc1
Answer: d. O=C(CCc1c[nH]c2ccccc12)Nc1ccc(S(=O)(=O)Nc2ncccn2)cc1
