Task: Answer the multiple choice question.
Question: Which drug has a -2.030\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) CCOc1ccc(N2C(=O)CC(N3CCN(c4ccccc4F)CC3)C2=O)cc1
b) O=C(COc1ccccc1Cl)N1CCN(c2ccc([N+](=O)[O-])c(N3CCOCC3)c2)CC1
c) CCOC(=O)c1c(=O)n(O)c2ccc(OC)cc2[n+]1[O-]
d) Cc1ccccc1C(=O)N=c1ccn(-c2nc3ccccc3nc2NS(=O)(=O)c2ccccc2)cc1
e) O=C(c1ccco1)N1CCN(C(=O)N2CCCC2)CC1
Answer: c. CCOC(=O)c1c(=O)n(O)c2ccc(OC)cc2[n+]1[O-]
