Task: Answer the multiple choice question.
Question: Which compound exhibits a 0.257\% 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 additional words.
Options:
a) CC1CC(C)CN(c2cc(N(C)CCO)c([N+](=O)[O-])c3nonc23)C1
b) CC(C)(C)C(=O)NCc1ccc(C(=O)CSc2nnc(C3CC3)n2C2CC2)s1
c) CCOC(=O)C1=CC[C@@H](c2cc3ccc(OC)cc3n2C)N(S(=O)(=O)c2ccc(C)cc2)[C@H]1C(=O)OCC
d) COc1ccc(CCNC(=O)CC(=O)N/N=C/c2ccc(Br)cc2)cc1OC
Answer: a. CC1CC(C)CN(c2cc(N(C)CCO)c([N+](=O)[O-])c3nonc23)C1
