Problem statement: Answer the multiple choice question.
Query: Which drug has a 4.139\% human ether-à-go-go related gene (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(NC(c1ccccc1)c1c(O)ccc2ccccc12)c1ccccc1Cl
b. CCOC(=O)c1c(C)[nH]c(C(=O)N2CCN(C(=O)OCC)CC2)c1C
c. O=C(COc1ccc([N+](=O)[O-])cc1)Nc1nnc(-c2cccnc2)s1
d. CC(C)C(NC(=O)c1ccc(C(C)(C)C)cc1)C(=O)NCC1(N(C)C)CCCCC1
e. CN(C)c1ccc(NC(=O)Nc2ccc3c(c2)nnn3C)cc1
Answer: c. O=C(COc1ccc([N+](=O)[O-])cc1)Nc1nnc(-c2cccnc2)s1
