Task: Answer the multiple choice question.
Query: Which compound exhibits a 15.719\% 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: C[C@]12CC[C@H]3C(CCC4(O)CC(O)CC[C@]34C=O)C1=CC[C@H]2c1ccc(=O)oc1
b: CCOc1ccc(NC(=S)N(Cc2ccc(Cl)cc2)Cc2ccco2)cc1
c: O=C(CS(=O)(=O)Cc1ccccc1)Nc1nnc(C(F)(F)F)s1
d: Cn1c(=O)c(=O)n(C)c2cc(N3CCOCC3)c(NS(=O)(=O)c3ccc(Br)cc3)cc21
Answer: a. C[C@]12CC[C@H]3C(CCC4(O)CC(O)CC[C@]34C=O)C1=CC[C@H]2c1ccc(=O)oc1
