Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 15.945\% 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: CCOC(=O)CSc1cn2c(n1)CCC2
b: CCOC(=O)N1CCN(C(=S)NC2CCCC2)CC1
c: Cc1sc2nc(CSc3n[nH]c(N)n3)[nH]c(=O)c2c1C
d: COC(=O)[C@]12OC[C@]34C([C@@H](O)[C@@H]1O)[C@]1(C)CC(=O)C(O)=C(C)[C@@H]1C[C@H]3OC(=O)[C@H](O)[C@@H]24
Answer: d. COC(=O)[C@]12OC[C@]34C([C@@H](O)[C@@H]1O)[C@]1(C)CC(=O)C(O)=C(C)[C@@H]1C[C@H]3OC(=O)[C@H](O)[C@@H]24
