Task: Answer the multiple choice question.
Query: Which compound has a 18.834% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] CC1(C)C2CC[C@]3(C)C(CC=C4[C@@H]5C[C@@](C)(CO)[C@@H](O)C[C@]56C[C@@H](OC6=O)[C@]43C)[C@@]2(C)CC[C@@H]1O
[b] Br.O=C(CN1C2=NCCN2c2ccccc21)c1cccs1
[c] COc1cc2nc(NC(=O)c3ccco3)sc(=O)c2cc1OC
Answer: a. CC1(C)C2CC[C@]3(C)C(CC=C4[C@@H]5C[C@@](C)(CO)[C@@H](O)C[C@]56C[C@@H](OC6=O)[C@]43C)[C@@]2(C)CC[C@@H]1O
