Task: Answer the multiple choice question.
Query: Which drug has a 1.811\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C(CCNc1n[nH]c(=O)[nH]c1=O)N1CCOCC1
b: NS(=O)(=O)c1cccc(NC(=O)c2cccc(Oc3ccccc3)c2)c1
c: Cc1cc(C(=O)NC2CCCN(Cc3ccccc3F)C2)no1
d: COc1ccc(NC2CC(=O)N(c3cc([N+](=O)[O-])ccc3C)C2=O)cc1
e: CCOC(=O)C1=C(COC(=O)c2cc(S(=O)(=O)N(C)C)ccc2C)NC(=O)NC1C
Answer: d. COc1ccc(NC2CC(=O)N(c3cc([N+](=O)[O-])ccc3C)C2=O)cc1
