Task: Answer the multiple choice question.
Question: Which drug exhibits a 5.378\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) O=C(NC1CCN(S(=O)(=O)c2cccc([N+](=O)[O-])c2)CC1)C1CCCCC1
(b) Cc1cccc(NC(=O)C2CCN(S(=O)(=O)c3ccc4ccccc4c3)CC2)n1
(c) O=C(NC(NNc1ccc([N+](=O)[O-])cc1)(C(F)(F)F)C(F)(F)F)c1ccc(Cl)cc1
(d) Cc1ccc([N+](=O)[O-])cc1Nc1nc(N2CCCC2)nc(N2CCCC2)n1
Answer: c. O=C(NC(NNc1ccc([N+](=O)[O-])cc1)(C(F)(F)F)C(F)(F)F)c1ccc(Cl)cc1
