Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 1.554\% 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 COc1ccccc1C(=O)NC(=O)CSc1nc2nc(C)cc(C)n2n1
b O=C(O)c1ccc(N=Cc2c(O)ccc3ccccc23)cc1
c O=C(c1ccc(S(=O)(=O)Nc2ccc(F)cc2)cc1)N1CCN(C(=O)c2ccco2)CC1
d CCCC(=O)O[C@]1(C(=O)CO)CC[C@H]2[C@@H]3CCC4=CC(=O)CC[C@]4(C)[C@H]3[C@@H](O)C[C@@]21C
e CC(Cc1ccccc1)N1C(=O)c2cccc([N+](=O)[O-])c2C1=O
Answer: c. O=C(c1ccc(S(=O)(=O)Nc2ccc(F)cc2)cc1)N1CCN(C(=O)c2ccco2)CC1
