Task: Answer the multiple-choice question.
Query: Which compound exhibits a 8.422\% 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) CCCCC(=O)N/N=C/c1sccc1C
b) CC(=O)O[C@]1(C(C)=O)CC[C@H]2[C@@H]3C=CC4=CC(=O)C=C[C@]4(C)[C@H]3CC[C@@]21C
c) CCOc1ncccc1C(=O)Nc1cccc(C(=O)Nc2cccc(S(=O)(=O)CCO)c2)c1
d) O=S1(=O)N=C2CCCCCN2C(c2ccc(F)cc2)N1
Answer: a. CCCCC(=O)N/N=C/c1sccc1C
