Task: Answer the multiple choice question.
Question: Which drug has a 13.959\% 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: CC(=O)N(c1ccccc1)C1CCCC1
b: CC(C)N(C(=O)Cn1c(SCC(=O)NCc2ccc3c(c2)OCO3)nc2ccccc21)C(C)C
c: C[C@]12CC[C@H]3[C@@H](CC[C@]4(O)C[C@@H](O)CC[C@]34C=O)[C@@]1(O)CC[C@@H]2C1=CC(=O)OC1
d: Cc1ccc(NC(=O)CSc2nnc(-c3ccccn3)n2N)c(Br)c1
Answer: c. C[C@]12CC[C@H]3[C@@H](CC[C@]4(O)C[C@@H](O)CC[C@]34C=O)[C@@]1(O)CC[C@@H]2C1=CC(=O)OC1
