Problem statement: Answer the multiple-choice question.
Query: Which compound has a 7.252\% 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) COC(=O)[C@@H](NC(=O)O[C@@H]1C(=O)c2cc(Br)ccc2O[C@H]1c1cccc(OC)c1)C(C)C
b) O=C(C1CC(=O)N(c2ccccc2)C1)N1CCCCCC1
c) COc1ccc(-n2c(SCc3ccc([N+](=O)[O-])cc3)nnc2-c2ccc(C)cc2)cc1
d) O=C(Nc1cccc(F)c1)/C(=C\c1ccco1)NC(=O)c1cccs1
Answer: a. COC(=O)[C@@H](NC(=O)O[C@@H]1C(=O)c2cc(Br)ccc2O[C@H]1c1cccc(OC)c1)C(C)C
